I was wondering what everyone here does when they can't solve a specific problem, be it one from homework or just one tackled on their own. How do you cope with that? Me, I get totally frustrated and angry, and I really want to change that. Today, for example, I really wanted to do some Physics reading, but when I got home I thought I'll look up some problems the professor posted first and try to solve the one that looked most interesting. Surely enough, I got stuck on it for 3 - 4 hours, banging my head against the wall (metaphorically), and in the end wasn't able to solve it. That completely messed up my day even though I tried telling myself to just move on and deal with other stuff. Still, I just get totally frustrated when I can't do stuff I was supposed to be able to do and it seems that no amount of rational thoughts can overcome my irrationality.
