Your job, should you choose to accept it, is to comment on this thread explaining the most awesome thing you've done this month. You may be as blatantly proud of yourself as you feel. You may unabashedly consider yourself the coolest freaking person ever because of that awesome thing you're dying to tell everyone about. This is the place to do just that.
Remember, however, that this isn't any kind of progress thread. Nor is it any kind of proposal thread. This thread is solely for people to talk about the awesome things they have done. Not "will do". Not "are working on". Have already done. This is to cultivate an environment of object level productivity rather than meta-productivity methods.
So, what's the coolest thing you've done this month?
Woah! I sure hope not! The two or three times I had challenging assignments in school (my school encouraged undergraduates to take graduate classes if interested) they were tremendously valuable. If thinking about difficult problems and solving them has no marginal benefit, I can't imagine what part of schooling does! (perhaps the diploma mill would be ideal in that scenario? I'm having a hard time simulating this hypothetical student).
It's not that it has no marginal benefit, it's that it has diminishing marginal benefit for the effort spent. At some point, you're better off working on another class's assignment instead. At some point you're better off taking leisure time, or even sleeping. If even people with a good understanding are only expected to get 50% correct, how are you supposed to know when you're better off going to sleep, only knowing that you've completed 50% and not knowing whether the extra 5% from sacrificing some sleep is worth it?
