When it comes to down time, I personally find it important to hole up for at least a day after an intense week of work. I've burnt out a couple of times in my career as a truck driver, and I atribute those burnouts to pushing too hard after a week or two of hard, stressful work. The toughest part of having to be "on" durring the week is having to pull out the reserves on the weekend when you get home for a family function or a last minute party. Like logic said, you NEED balance, or the house of cards will come tumbling down.
Personally, the first thing I do when I get home is give all of my friends a polite "fuck you", go home to my girlfriend and have a stiff drink. After a good night of sleep and taking care of things in the morning, I then call my mates and see what's up. I don't go out of my way to run to any party, I don't go out of my way to help anyone, I do what rob wants to do. As a friend so eloquently put it once... "What's Rob doing? Anything Rob wants."
