You don't have to be anything but yourself. I know this to be true because I was formerly an entertainer and as an entertainer, one would have bend forward, backwards, sideways and under just to please the audience. It will take a toll on you if you allow other people to usurp your power to be just you. I spent a large number of years trying to prove to others that I was capable of things and that I was worth much more than they gave me credit for. I have never felt so alone and given-up-on in my life. Those years forced me to be stronger, become more aware of what I am made of and the kind of power I have inside of me that I wasn't making use of. I cared so much about what others thought about me that I forgot to like myself. I abandoned the idea of taking care of myself, and instead started proving to others what I am made of. Don't. Forget it. If they don't see it in you, see it for yourself. Enjoy your own company and love whatever mistakes and flaws...
