not something you want to regret

For the longest time, I wanted to be a doctor. I decided in college that first I wanted to serve the country so I became a marine. Now that it's getting close to me getting out of the marine corps, I don't want to be a doctor anymore. I want to find a job that I love but I want to hear all about the jobs other people have first and their experiences with it! Where do you work? Pros/cons!
