Strong Will Is Like a Muscle. How to Practice It?

Have your cake and eat it too? A few words on gratification

Every day, we all feel an inner drive to act, aimed at satisfying various needs. These can be simple physiological needs, such as obtaining food, or more complex ones, like wanting to understand how an airplane stays in the air. This impulse that drives us to act is what we call motivation. But what happens when it’s hard to stay on course toward a set goal?

What often helps us get motivated to act is a reward. We are happy to take on tasks when we know the gratification will be immediate. For example, when we are rushing to catch a tram, running a few dozen meters to make it is easier because the reward—the fact that we made it—appears almost instantly. It’s different when we want to run to improve our health; we must persevere with our training, and the reward is distant in time.

Many studies indicate that people who can persistently pursue a goal without giving up despite delayed gratification—for example, by continuing training, studying, or acquiring new skills—achieve more success in life. Talented athletes are a prime example; to win medals, they had to spend many hours training and put enormous effort into their athletic development. So, what distinguishes those who expect immediate gratification from those who can patiently wait for it?

To understand this difference, it is worth recalling the famous study by Walter Mischel and his colleagues, known as the "Marshmallow Test." It involved children aged 3 to 5. Each child sat at a table with a marshmallow or another treat. The children could eat the treat immediately or wait for the researcher to return, who—in exchange for their patience—would give them two treats. The researchers observed that many children who wanted to earn the larger reward used various strategies to resist temptation. Some covered their eyes, looked away from the treat, or engaged in distracting activities like singing. Others quickly gave in to temptation and ate the treat.

Later studies showed a correlation between the ability to delay gratification at a young age and positive outcomes later in life, for example, in areas like academics or stress management. Research conducted by Walter Mischel showed that people with strong willpower often use strategies such as distraction or changing their environment, which allows them to avoid temptations.

Instead of relying solely on willpower, we can arrange our environment in a way that supports our goals. For example, we can avoid keeping unhealthy snacks at home or turn off phone notifications while working. These findings suggest that willpower can be strengthened through appropriate environmental changes or cognitive strategies that reduce temptation and make it easier to persistently pursue a goal.

Can willpower get tired?

Roy Baumeister and his colleagues conducted some very interesting research on self-control. His "ego depletion theory" suggests that human willpower is fueled by a limited pool of energy. The studies confirming this thesis were conducted in four phases—one of which involved resisting temptation. The participants' task was to refrain from eating snacks. They were presented with two types of snacks: freshly baked cookies, which the researchers considered a very tempting option, and radishes, which were considered less appetizing than the cookies. The participants were divided into three groups:

• the "radish" group, who were told to eat only radishes,
• the "cookie" group, who were allowed to eat cookies,
• the control group, who were not given any food.

Next, participants were asked to solve puzzles that were designed to be unsolvable. This task was intended to test their persistence, a measure of self-control. Those who had been tasked with resisting cookies gave up on the puzzles faster than participants in the other groups. The researchers concluded that the self-control required to resist the cookies depleted their willpower, leaving them with less mental energy for subsequent tasks.

This is a very interesting concept, suggesting that long-term suppression of an urge leads to a depletion of energy resources, which in turn weakens our ability to stick to our resolutions. However, the validity of this conclusion is not certain—when scientists attempted to replicate these studies with different groups of people, the ego depletion effect was not observed.

How to train your willpower muscle?

How can you support your own capacity for self-control? Scientific research suggests several effective strategies:

1. Strengthening the prefrontal cortex. Impulsivity can contribute to abandoning long-term plans and weakening our willpower. For example, while out for a walk, we might see a beautiful jacket in a shop window (which we don't actually need) and feel a sudden urge to spend our savings on it. In such a situation, a well-developed prefrontal cortex can be helpful, as it allows us to understand and anticipate the consequences of our actions, supporting us in saying "no" when faced with sudden temptations. Solving puzzles, reading, or concentration exercises stimulate this part of the brain.
2. Maintaining proper blood glucose levels. Research suggests that blood glucose levels play an important role in supporting self-control. It turns out that tasks requiring self-control can lower glucose levels in the brain. Replenishing them through food or drink can provide us with energy and help restore willpower. Long-term improvements in self-control may also result from improving the body's ability to regulate glucose levels (e.g., through diet and regular physical activity).
3. Implementing simple plans. Setting clear goals is important when exercising willpower and self-control. When we encounter difficulties in achieving them—such as procrastinating, getting distracted, or falling into unhelpful habits—we can refer back to our earlier arrangements. It is worth creating simple plans based on the "if-then" principle. For example: "If I feel the urge to procrastinate, I will start the task immediately and stick with it for at least 5 minutes." This technique, developed by Peter Gollwitzer, helps "automate" responses to common temptations, reducing the burden of decision-making and saving willpower for new challenges.
4. Practicing meditation. Mindfulness meditation is a scientifically proven way to develop self-control by improving emotional regulation and concentration. A 2012 study by Michael Inzlicht showed that people who practice mindfulness meditation are better at controlling impulsive actions. This is mainly because regular meditation strengthens the function of the prefrontal cortex.

Many of our life ambitions and goals require long-term, consistent effort and vast energy resources. We have all likely heard or said the words, "I lack willpower." However, remember that regardless of our personality traits, everyone has the potential to better support themselves in achieving their goals. Research shows that there are many ways to "overcome" the weaknesses of our willpower.
