Most people who do creative/analytical, solitary "desk job" work burn out at some point. Writers get writers block, composers go mad, mathematicians solve the Poincare Conjecture then disappear off the face of the earth.

Programmers have the worst burnout potential, because in addition to the unpleasant parts of the job itself, you have to deal with some of the most obnoxious personality types on the planet, and do all your work on a machine that is conspiring to ensure you never get anything done. It's assumed other solitary creative/analytical types are oddballs who take tons of time off to recuperate between projects, but programmers are expected to produce day in and day out. There's also the looming archetypes of the superhuman guy who writes 3D engines in his spare time and the billionaire PHP programmer, making you feel bad about both your abilities and bank balance.

As a general salve, I turn off the internet for days at a time, spend time with friends as much as possible and go to the gym. However, none of that is as effective as not working with bozos, and not working on projects I don't care about.
