I've never been a fan of summing up one's life in a few words. But a guy by the name of Brian Andreas, who has a business called Storypeople, made a good run at it for me.
Since its probably too small to read, here's what it says:
I hope it will be said we taught them to stand tall & proud, even in the face of history & the future was made whole for us all, one child at a time.
Anyone who takes on this kind of work in life must first be honest with oneself about why it has become such a passion. For many of us its because we want to give children what we have learned (often the hard way) is essential in life. One of my lessons has been that when there is no one there to take care of you - you have to do it yourself.
