is it better to try and screw up and face whatever consequences there are, or don't try at all?

today i was repairing my bike, some stuff wasnt right, and i tried to fix it. while fixing it, i accidentaly caused a new problem, and the previous problem was still there, and now there were 2 problems. after much sweating and worrying, i decided to leave it and go to a bike shop tmr to get it repaired.

and chinese Os are in a week. i know i should be studying, but i dont feel like studying, as usual. but then again i will study, eventually. after chinese Os...woohoo!
