Define Success

I am a husband, a father, a son, and a brother. I am a writer, a reader, a musician, and an artist. I am youth leader, a conference presenter, a learning community member, and a mentor. I am a photographer, a gamer, an athlete, and a napper. In my spare time I teach.
I am a practicer of many things, but a master of none. Because I do so many things I fail regularly and spectacularly. I share my failures and the occasional success.
I agree with some opinions, disagree with others, and often have no opinion at all.
Am I a successful adult? If so, why am I successful. If not, why not? Was my education successful?
