Speak for yourself. Some of us have been there, burnt out and had to rebuild our relationship with work in a healthy manner. I think no matter what you do, if it is thought work and you don't find a wat to turn it off, you are doing yourself a diservice.
I loved what I did for 10 years, then all of a sudden I didn't. It was like my brain had cottoned on to the fact that software was where all my stress came from and I felt ill even thinking about sitting at a computer. I have rebuilt my relationship with software into a more healthy one since then, but it bares mentioning time again. The software industry will burn your wick at both ends and then toss you asside when you're no longer young and stupid enough to work more than a normal work week.
Sorry to be so cynical, just be careful is all.
