I no longer have to get out of my warm bed and drive to work
This used to be the worst part of my day- getting up and fighting traffic to get to work. Well, the work kinda sucked too, but the drive was the most aggravating part of the day.
I retired in 2006, and have since gone back to work, but on my own terms. I work from home, and have very flexible hours.
I can't imagine ever going back to work where I'd have to drive into an office every day.
