Don’t let people know too much about you.
Most people are an open book. Don’t be like most people. You have the option to keep your mouth shut. Only talk to those who are going to benefit from what you say, even then, be careful. Keep to yourself and only talk when needed. People confuse silence with awkwardness and not realize that you don’t need to speak all the time. There are going to be times when it’s better to say nothing and make sure you understand those times.
