Controlling your willpower requires your inner strength. There is also the cultivation of your own interests, which requires your strong love for your own interests, so that you are willing to do your own thing patiently while others are playing. At the same time, a good self-satisfaction is to learn to calm down, talk to your inner self and learn to be yourself instead of doing things you don't like.
People always grow up slowly. Don't force yourself to grow. Do what you should do at this age, so that you have no regrets and have learned everything you need to learn. Therefore, willpower is actually a requirement for yourself and a person's inner desire.
