What does it mean for you to be proud? Is it something you're happy about because you accomplished a goal? Are you proud of your friends because of the impact they have made on you? Are you proud of the people you come from whether experience is good or bad, that has shaped you into the person you have become? Above all, you have to be proud of you. If you're not there yet, then thats ok. Address the situation and do what you can to change that.
