Also a good question, and after much thought, I would have to say my brother. He fought through his first year of life to make it 24 more, has lived with a life-threatening heart condition most of his adult life (but to meet him, you wouldn't know it), and is blessed with this amazing artistic talent that he has harnessed and will do wonderful things with. Not to mention the fact that he would give the shirt off his back to a stranger in need.
What is your biggest goal in life, and have you achieved it?
