I'm the same way. I took a year off once, and it was awesome. I regret not being a lucky trust fund kid.
I don't understand these people who can't find things to keep them occupied outside work. I don't have enough hours in the day to do all the things I want to do. Work is just 8 hours per day that I can't do those things.
Plus, being able to attend events spontaneously and stay out as late as you want is pretty great.
