Never give up. Never ever give up. Never ever, ever give up.
Giving up begins with looking for excuses to cut away the precision in the work you’re doing. You find ways to justify rubbing the precise beauty in your work, life, practice, etc… and when things get messy and ugly, you throw up your hands and have a reason to walk away (why should I be the one to fix this mess? better to just capitulate and move on.)
But we can’t do this and we can’t even think of doing this. We must never give up.
