You could give up, but then the wood wins, and really you can’t have that. What an affront to your ego!

No, the better course is to make that project regret crossing you, by learning where you went wrong and doing it better next time. Weep over that, glue marks! Learn your place!

In all seriousness, can’t help with your first question but I’ve fucked up more often than I’ve gotten things right, and it’s wicked demoralizing, but that’s the process to improve. If you were perfect at everything right from the start, where would be the fun in even doing it? No growth no challenge.
