Rationality is the ability to think logically and make decisions based on reason rather than emotions or impulses. It involves evaluating information, weighing options, and considering the consequences of actions. People who are rational often seek evidence and use critical thinking to solve problems, making choices that are more likely to lead to positive outcomes. In everyday life, rationality can help us navigate challenges, from simple decisions like what to eat for lunch to complex issues like financial planning. By applying rational thinking techniques, individuals can improve their judgment and achieve their goals more effectively, leading to better overall well-being.
