The first thing to do is to remember to divert your attention when you are confused and negative. When you pay too much attention to the negative things that confuse you, you will have less and less attention to other positive things. Just as you are too nervous to sleep because you are too worried about tomorrow's graduation defense, if you continue to think about it in bed, if you don't speak well tomorrow, or if you are too nervous, it will lead to all kinds of major mistakes. Then you can't sleep. But if you try to divert your attention, admit that you really care about the defense, and then get up and do something else that will make you feel at ease. For example, listening to a complete light music, or reading a complete short story, or writing a diary. This kind of distraction can help you avoid spending too much time and energy on "what you are afraid of" So, when you feel negative and confused, leave your environment for a while. Don't stay at home, don't stay in the dormitory and don't lie on the sofa. Go to the gym to run and practice abdominal muscles, go to the bookstore to read books, climb mountains, go swimming, and try anything that can distract your attention. When we were young, we always heard such an idiom called "full of energy". At that time, I thought that the spirit and the body can actually be separated, and even if one is in poor health, one can maintain a state of full spirit. I didn't know until I grew up that mind and body are actually one. If a person does not exercise for a long time and is unhealthy, it is difficult to be energetic and healthy. Because he even needs to spend a lot of time and energy to maintain basic physical health, there is little left for the spiritual level.
