I've actually enjoyed working from home for the most part over the past 5-6 months. My only main issue is that I tend to work MORE from home as you don't have the normal water cooler interruptions or group BS sessions about football or sports or... this or that. I'm hoping I don't ever have to go back to the office.
Worked from home for a few years in the old days but wasn't really disciplined to be very productive. Now I am.
