I wish I had done more internships at college.

I wish I planned out my career. I'm in my mid thirties and it is really hard to job hunt without a cohesive story about what you have done and what you are moving towards.

I wish I had moved to a big city ASAP. Big city means more jobs, more money, more young people.

I wish I put more time and effort into communication and emotional skills. Technical skills are not the most important thing.

My overall advice for college agreed people: do a small scale version of what you want to do as a career. It could be as a small side project, with a friend or as part of a college club. Do it in a rough way, but finish it and make something. You learn a lot by taking something to completion.
