Personally? To get published [http://www.escapistmagazine.com/forums/read/18.72168] and be, at the least, moderately successful at it. Even better if I continue getting checks.
Otherwise, perhaps become a permanent/professional writer for a group or community specifically devoted to something I like. I'd take anything from writing goofy, fake news articles for The Onion to working here at The Escapist. So long as I enjoy it, it'd be another one of those life-accomplishments I'm working toward.
Lastly, own a coffee-shop. I really, really want to own a coffee shop, and generally hang out in a nice, warm, comfortable atmosphere with customers, being at ease and happy.
