Growth mind set is the concept of quantity and quality. We're often told that we need to focus on quality in things like the 80 20 rule, or the quote around if i had to chop down a tree, i'd spend three hours sharpening the axe and 20 minutes cutting,. et cetera. It makes you think that you really need to overplan things and do things completely perfectly the first time. And it stops you from finding aflow in just doing stuff. If you go the opposite way and go for quantity over quality this will help you improve.
