"Who am I? Why am I here? You're asking, I'm asking. Tired of all the moaning around me, tired of waiting for something to happen, I decided that I couldn't just let life pass me by. It occurred to me that if I could help a single person, that act could change the outcome of an entire community for the better. I want to matter. I want to make a difference. I've chosen Nicaragua." That was 2011 - this is 2017.
