“Be yourself” this is a piece of advice and the best thing that you should do. Why is it so hard for other to show what they are? They maybe want to impress others or they maybe have secret to hide. It seems that people afraid to reject and play as puppet. Somehow, it is really hard to be yourself if you keep o thinking of what bad comments and thoughts that will people tell you. You are not born to be like him or her. Being you is always worth more than being a copy. Show your own color. Is not about to impress other people, it is creating a better you. You do not need to accept by others, it is you to accept yourself.
Be someone that is unique, someone that is not copy and fake same, someone who understand you, someone that is unlike others. Be yourself no matter what. Who cares?
Be yourself nobody is better qualified!
