Your story makes me want to cheer.
The opportunity to be great is close at hand for most of us, though seldom will our greatness bring us fame. We pursue it every time we step outside our comfort zones to do what must be done, ignoring the fact that no one "like us" ever did before.
The key is to remember, no one like us ever was before. We are--every one of us--the universe attempting to do something it has never done.
