Learn to make up your own mind, don't ask for other people's opinions in everything, get rid of inferiority, learn to be independent and find confidence.
It is difficult for a person without self to do great work, so his life is useless. We should always hint at ourselves, motivate ourselves and tell ourselves that I can do it.
Even if some tasks are not perfect, you should encourage yourself. You don't have to do everything perfectly. Nothing in the world is perfect. Don't cling to some mistakes in your work, and don't care too much about other people's opinions.
