The way I see it you aren't a nobody if you strive to help out others, and maybe make their day a little brighter. Will most of us end up in the history books, no. But you aren't a nobody, you may not be built with muscles like Schwarzenegger, but very few are. I think you are doing the best you can, and with any luck things will improve. We can't control our health or genetics, but you have a life and you have your faith. That's what matters most!
