Thankfully there is often a pretty big difference between studying and working.
I found there to be a level of stress in my studies that I never had a problem with later. An idea that any moment not spent pouring over books was contributing, at least in my mind, to inevitable failure; doubly so with exams looming ahead.
For me finishing my engineering degree was such a massive relief and work is so much better. I'm in anon's boat.
Didn't some early 3d pc games have this effect as well? I vaguely remember the wobbliness from the first Quake (or was it unreal? Can't remember).
