Can you give some more details of how you currently spend your time? Live in a city? How many hours do you work? How long is your commute? Do you work weekends? Live alone?
Work (enjoy what I do) ~40 hours/week. Commute is about 20 minutes one-way. No weekends anymore, thankfully. And yes, live alone. Free time spent reading, tv, WoW, learning. I try to hang out with a friend at least once a week for a few hours
