don't kill yourself trying to do everything on hardcore if it's not working out. i'd rather have a line i really like that is fun to do than one that takes 2-3 hours and doesn't match what i wanted anyway. my last couple have been on normal and people didn't seem to mind.
alot of times i have idea for things i want to do, but then other things happen, and at that point i'm so frustrated with spending an hour trying to get this fucking line done that i just say "ok that works" i wanted to flip trick the bank but i spent an hour just trying to get the first grind down right that i just went with what i have. when i'm not raging at the game i'll probably try again.
