I sort of understand it from the students' perspectives, because they have a professor to compare themselves to and aspire to, I think in that scenario it spurs self-improvement but in the workplace it seems like it would only be counterproductive at best to compare yourself to other coworkers or even other people in the field.
I remember when I first started, I never thought "Shit, will I ever be as good at Scheme as Sussman?" I just worked the exercises and kept moving forward.
Nowadays, there seems to be a real strong pressure to be aware of all the new technologies, newest libraries, and all this material that nobody could ever possibly have time to completely understand, and it drives people crazy, I think.
