I have to believe in my self

I know I have many good capabilities. But I never challenge this with anyone. I never thought I am the best in it. I always thing there are always possibilities to upgrade myself and there could be other who are better than me. But I don’t take any leading position by myself, coz I wanted to give chance to others. And most of the time I found, I were the better skilled person. But I never regret for this attitude. I took only those responsibilities which are given to me. May be I have to believe in myself little more, to give better service to other. I know I can do it.
