Don't chase people. Be yourself, do your own thing and work hard. The right people - the ones who really belong in your life - will come to you. And stay.
-Will Smith-
The number of characters played by Will in his career has no influence on him being himself around others. Don't try to be someone that you are not (unless you are acting), and don't let others have too much control over your emotions. Be yourself, as the Man in Black did.
