The so-called self-control is a person's ability to control his thoughts, feelings and behavior. One of the fundamental differences between humans and animals is that humans can rationally control their emotions and actions according to certain purposes. Self-control is an important indicator of whether a person is strong. A good life is based on self-control. When you can control your lazy mentality and change bad habits, you can control your own destiny and avoid falling into an out-of-control whirlpool.
