I can't imagine going back. I'm a marketing consultant (going on 20 years) and am typing this in my dining room in my pajamas (early conference call and I have dinner plans, so figured I'd just shower and get dressed later).
Whenever I have to be in a corporate office, I am reminded of all the reasons I could never stand to go back. Cubicles, meetings after meetings after meetings. Co workers! Lunch breaks? 2 weeks of vacation?????
Think carefully, OP. No released prisoner ever thinks "You know, it really wasn't that bad inside...."
