Actually, as a full time writer, weekends don't mean that much to me. I write every day, and I often find that going out and doing fun things during the week when everyone else is at work is cooler and less crowded than waiting for the weekend.
I still do a lot of the things I did when I was younger. I go to the movies. I go to clubs with my girlfriend. I play computer games. I read. Same old same old.
