Can't say that I would quit my job, because not working at all would be boring as hell. Maybe get an agreement to consult or do part-time work. I would have to have something to do, maybe get into charity work.

Upgrade my residence and vehicle somewhat, but nothing too extravagent.

Use extra spare time to play more video games. What can I say, I'm a geek.

Can't say I would better myself, but I can't see myself going downhill either.
