Second, form firm habits.
Self-discipline is really hard to bear, because it is boring. At this time, it shows the importance of habit. After forming a habit, you don't need to spend too much willpower to maintain it. As long as regular habits make you form a stable biological clock, then you can maintain self-discipline day after day.
Third, give yourself only five seconds at first.
When you want to start a job, recite five numbers 12345 in your mind and do it at once. This is a very useful method, which has pulled me back from the brink of procrastination countless times.
Finally, conform to human nature.
Don't do that kind of self-discipline like an ascetic
For example, a handsome guy with eight abdominal muscles is self-disciplined because he will enjoy the envy of others. These desires can help him overcome the emotion of eating fried food. But if you let a person who takes eating as a pleasure in life give up food, these are obviously unrealistic. So follow your wishes and make it concrete, preferably with numbers, such as how many books I want to read, how much weight I want to lose, and how many points I want to take in the postgraduate entrance examination. Write it down and put it where I can see it.
