I agree that flexibility is probably one of the rewards. People often ask if I get bored and I tell them "How can I get bored when I can do whatever I want to on pretty much any given day?" We don't have to sit at home if we don't want. We can work from Starbucks, the beach, you name it!
Chet, You hit the nail right on the head, having people hang over your every move is unpleasant.
I think working to solve problems and to make people some extra funds in this trying environment, is gratifying. Working from home and not paying $4.00 and over for a gallon of gas, is a plus!
