Character is who you are, how you treat other people, and whom and how you love. Be you, and be satisfied with that. Always work to improve what and who you are, but never feel that you'll be better for having some thing. You are who you are for a reason, and the world needs you to be just who you are, and to be that person to the best of your ability. Covetousness bursts the sack and spills the grain.
Every ambitious person is a captive and every covetous one a pauper.
