Willpower is the ability to control one's impulses, emotions, and behaviors in order to achieve long-term goals. It involves making choices that align with personal values, even when faced with temptations or distractions. This mental strength helps individuals resist short-term gratification for more significant rewards in the future. Research shows that willpower can be strengthened through practice, much like a muscle. Factors such as stress, fatigue, and environment can impact a person's willpower, making it essential to develop strategies for maintaining focus and motivation. Building good habits and setting clear goals can enhance one's ability to exercise willpower.
