I can't say that I have a strong desire to promote any cause over another. Certainly, everyone has his or her strengths and a unique perspective on the world. Because of this some people are better suited to bring awareness to certain topics than others.
However, I think that we should all push to find the best of ourselves in as many ways possible. We should test our limits in every way. Defining ourselves by a single "cause" may stop us from making an impact where we never thought possible.
