What Is Willpower? The Psychology Behind Self-Control

We all wish we had more willpower, self-discipline, and self-control.

After all, think about what we could do–and all we could achieve–if we did.

Several researchers believe increasing our understanding of willpower and self-control may be psychology’s best hope for contributing to human welfare (Baumeister & Tierney, 2011).

After all, the wealth of self-help books at the airport suggests we all need some help to form good habits and being more disciplined as we work towards our goals.

This article digs deeper into the psychology of willpower and the tools available to boost it.

What Is Willpower? Its Meaning & Definition

Neuroscience tells us that our prefrontal cortex–the part of the brain just behind our forehead–controls what we do. It directs what we pay attention to and think about–and even the emotions we experience (McGonigal, 2013).

So, when we put things off, watching TV instead of completing the tax form, that’s our prefrontal cortex at work.

And yet, this part of the brain is more than a single unified decision-maker. It has three key areas, each one helping us weigh up whether “I will,” “I will not,” or “I want” to do something.

The left side of this brain region helps us stick to tasks (I will)–even boring ones–while the right side (I will not) stops us from being distracted or giving in to temptation. Finally, in the middle, but lower down in our prefrontal cortex, the cells fire to keep us motivated and in line with our goals (I want) (McGonigal, 2013).

Sometimes, because of the ongoing competition within our brains, we fail. We don’t have the willpower to stick to the diet or get to the gym. Other times, we maintain the drive to push on, despite other interests, temptations, and distractions. Willpower is evident in the latter.

And “anyone with some life experience under their belt knows that they can accomplish more with a healthy sense of constraint and willpower” (Hollins, 2021, p. 15).

So, where does this leave us with our understanding – its meaning and definition?

According to the American Psychological Association (APA), “willpower is the ability to resist short-term temptations in order to meet long-term goals.” (American Psychological Association, 2012, para. 7).

We could define willpower and see its benefits as (American Psychological Association, 2012):

• Resisting short-term temptations and delay gratification to achieve long-term goals
• Overriding unwanted thoughts, feelings, or impulses
• Responding coolly and calmly rather than behave too emotionally
• Conscious, effortful regulation of oneself by oneself
• A limited resource that can be depleted

Understanding willpower is essential to recognizing why we behave as we do and how we develop our resilience.

Research into patients’ ability to combat disease and illness suggests that it is “willpower that gives an individual resilience to overcome difficulties” and “that which our heart and mind do not desire, we will not have the willpower to obtain” (Amdie, Sawhney, & Woo, 2022).

The Psychology Behind Willpower

“Whether you think you can, or you think you can’t – you’re right.”

Henry Ford (Goodreads, n.d.).

For a long time, psychologists thought of willpower as a limited resource—known as the ‘ego-depletion theory’ (American Psychological Association, 2012).

Work by Roy Baumeister led to the view that willpower is finite and–just like energy when muscles are overworked–can be used up. In his famous ‘cookie’ experiment, people who could resist eating them right away (called delayed gratification) had a more challenging time controlling temptation later in other tasks (Baumeister & Tierney, 2011).

The theory suggests that if you set more than one self-improvement goal, you may draw on willpower reserves, leaving you depleted and risking failure (Baumeister & Tierney, 2011).

And if willpower is a limited resource, we must use it wisely to achieve long-term goals (American Psychological Association, 2012).

And yet, recent and contradictory psychological research and theory suggest there isn’t a fixed amount of willpower. “Instead of thinking of willpower as the amount of petrol in a car…think of it as the car’s battery,” says Krishna Savani from Nanyang Technological University (Jarrett, 2018, para. 3).

Savani believes that with the right mindset and motivation, we can ‘own’ our self-control and willpower. And this is backed up by data. Studies show that people are less likely to quit a task when told their resolve is not fixed but unlimited.

While building willpower is not easy, psychology suggests that “a huge part of the solution is simply believing that you can do it” (Hollins, 2021, p. 36).

So, what happens when we do and don’t get things done?

It seems that mindset is crucial. Students coming up to exams that were told willpower was unlimited experienced less stress, fewer bad moods, and could step up their efforts. If we ‘believe’ we have the reserves available to tackle the challenges ahead, we increase our chances of future success (Jarrett, 2018).

4 Admirable Examples of Willpower

The following three powerful examples highlight the potential for willpower to change lives.

The first shows how it is possible to lose our strength of will and how it is influenced by the brain’s anatomy. The second shows the value of willpower in sports and the final displays the potential of good habits to improve business performance.

The curious case of Phineas Gage

While working on the railways in 1848, twenty-five-year-old Phineas Gage suffered a terrible accident. An iron rod pierced his skull at speed following an explosion, lodging itself in his prefrontal cortex. Although he survived the head injury, he experienced extreme changes to his personality, language, intelligence, motor functions, and self-control.

Previously calm, focused, and mentally strong, he was now impatient and impulsive. His friends described him as no longer being Gage—he had lost his most admired qualities, particularly his willpower.

The damage to the part of the brain we now know is associated with self-control meant that he no longer had the willpower to see tasks through to the end or to stop himself from succumbing to temptation. He never fully recovered (Zeigler-Hill & Shackelford, 2020; McGonigal, 2013).

A baseball legend

Kobe Bryant was an American basketball player widely regarded as one of the greatest of all time. He was known for his strong willpower and determination throughout his basketball career.

And yet, having joined a summer basketball camp at age 12, he didn’t score a single point. He was ready to give up on basketball, but then he read about how Michael Jordan was cut from his high school basketball team and how it became his motivation to outwork everyone around him (Robertson, 2016).

The story inspired Kobe to follow in Jordan’s footsteps and become the hardest worker in the game of basketball. He began showing up at the gym at 5 am and not leaving until 7 pm while in high school. He put himself through four hours of intense workouts even on game days, played one-on-one games up to 100 points after practice, and worked on his skills with no one else or a ball to perfect his footwork.

Michael Jordan was a role model and inspiration for Kobe, greatly influencing his willpower and motivating him to achieve his goals.

Sadly, Kobe’s life was cut short by a devastating helicopter crash in 2020 that killed him and his daughter, yet he was to become an inspiration for his fans, and his commitment a lesson to us all (Gooden, 2022).

Making a stand for civil rights

Rosa Parks never imagined that her bus journey home would result in her becoming a figurehead for the US civil rights movement.

And yet, on December 1, 1955, when she was arrested for refusing to give up her seat for a white person, it led to a 381-day boycott and the ultimate repeal of racial segregation on buses (Bredhoff, Wynell, & Potter, 1999).

Rosa Parks’ strength of will caused one small act of defiance that was part of something that changed history and her being called by the United States Congress “the first lady of civil rights.” (Wikipedia Foundation, 2023).

Creating good habits to boost willpower

James Clear talks about the importance of good strategies in his book “Atomic Habits” and offers the following example of how they can drive willpower (Clear, 2018).

When Trent Dyrsmid began his job at a bank in 1993, he was young and inexperienced – so no one expected much from him. And yet, he formed a powerful habit that boosted his commitment and willpower.

He started each day with two jars: one with 120 paper clips and the other empty. Each time he made a sales call, he moved one paperclip from the full jar to the empty one. He wouldn’t stop until the first jar was empty.

It sounds simple, and yet “[w]ithin eighteen months, Dyrsmid was bringing in nearly $5 million to the firm.” (Clear, 2018, p. 196). He was successful because the good habits he put in place drove his willpower and facilitated his desire for success.

How to Increase Your Willpower

Whether you believe willpower is a limited resource or something that can be ‘re-filled,’ there are many ways it can be increased.

Here are some actions and behaviors that can help boost your willpower (Jarrett, 2018; American Psychological Association, 2012; Baumeister & Tierney, 2011; McGonigal, 2013; Clear, 2022):

Strengthen your mind

“Psychological discomfort is created because you know you are avoiding your responsibilities, so you engage in a distraction to alleviate that discomfort.” (Hollins, 2021, p. 48). The following exercises can help strengthen your mind, helping you to not take the easy option, for example, choosing unhealthy eating habits or remaining inactive:

1. Practice mindfulness meditation
   To improve self-control and help individuals act from intention rather than habit or craving.
2. Get enough sleep
   Physical and mental fatigue can decrease willpower, so it’s essential to maintain energy levels by getting sufficient and good quality sleep each night.
3. Use food- or fitness-tracking apps
   Tracking what we do or don’t do can help individuals make healthier eating choices and provide encouragement to get up and move by tracking movement and exercise.

Develop your personal control

When we have confidence in our abilities and believe in our willpower, we are better able to keep or regain control (Hollins, 2021).

1. Set clear and specific goals
   A clear understanding of your goals can help increase motivation and self-control.
2. Break down large goals into smaller, more manageable tasks
   Smaller chunks of work that build up to larger goals make it easier to focus on progression and stay motivated.
3. Work with a mental health professional
   Therapists and counselors can provide guidance and support in increasing willpower and building healthy habits.

Delivering your full potential

Sometimes our biases change how we see opportunities and make us focus more on risks than benefits. Making decisions based on reason can help us realize our full potential along with a kinder, more optimistic view of what we have to offer (Hollins, 2022).

1. Challenge yourself
   Push yourself out of your comfort zone by taking on complex but not impossible tasks. Practice and repetition will boost willpower.
2. Practice self-compassion
   Be kind and understanding with yourself when you make mistakes or stumble, and don’t let setbacks discourage you from continuing to work on increasing your willpower.
3. Get support from others
   Surround yourself with people who encourage and support your efforts to increase your willpower.

It’s essential to remember that willpower is like a muscle and that progress may not always be immediate or linear. Furthermore, like physical exercise, our mental resolve and self-control can be strengthened with practice and pushing against perceived limits.

Note that there is no “right” amount of willpower, but we ought to develop what is needed to live a happy, healthy life where we flourish (Seligman, 2011; Jarrett, 2018).

Step 4: Add more pleasure and mastery activities into your day
Step 5: Plan more energy giving activities

A Take-Home Message

Willpower, self-discipline, and self-control are valuable abilities that can help us achieve our goals.

Willpower provides us with the ability to resist short-term temptations while we focus on long-term goals, giving us the capacity to override unwanted thoughts, feelings, and impulses. When strong-willed, we can respond coolly and calmly rather than rashly and emotionally.

Some believe willpower is limited, while others consider it something that can be re-filled and infinite. Either way, it can be grown, becoming a habit that we can practice daily through learning practical strategies and pushing ourselves toward new challenges.

Studies suggest people are less likely to quit a task when they believe their willpower is unlimited and that a considerable part of the solution is simply thinking that you can do it.

Work with your clients to understand how and when their willpower may lack and how it stops them from achieving what they want. Work with them to help them realize the unbounded nature of willpower and try out some practices shared within this article to become their best selves.
