Here are the ways to mature yourself:
1. Talk less. Try to be a person who talks less. If you chatter and make noise all day long, you are like a child. You talk when you see people. Saying everything is childish. You must understand that trouble comes from the mouth and talking too much will lead to mistakes.
2. Be less playful. If you want to grow up and mature, tell yourself to play less games every day, which will waste a lot of your time.
3. Complain less. If you want to be mature, complain less and don't complain about the injustice of fate. Complaining is a sign of cowardice and psychological immaturity. Mature people know how to face life positively and optimistically.
4. Use your brain more. Think before you act, don't be too impulsive, know how to control your emotions, know what a true friend is, what you should do and what shouldn't be done.
