Stay humble, hungry, hidden. Always try to be composed, always seeking more knowledge and understanding, you don’t need to always say stuff. Not because you are, you did, you are doing means every one has to know.
The more mature you become, the less you talk, the more you observe and understand people and the world around you. You learn not everything you react to, even when you have your right you stay quiet, learn something from every situation.
Don’t talk much when you are angry, when someone is that’s the time to listen, expect a reaction to every action. Don’t be selfish, when you can take yourself out of everything, your way of thinking changes. You will have your right and loose it because of what you say and do.
