Do -> analyze strengths and weaknesses -> try to do better.
That middle part is way more successful with the help of a good coach. Really quick learners ("talent") can fill in that middle step on their own, but would ultimately benefit from a coach.
When your work cycle is:
do -> do again -> do again -> do again
you'll improve a bit, but pretty quickly plateau.
Now and then I see 'self-help' or motivational type pieces encouraging a type of "Focus on your strengths, not your weaknesses" which can be applicable in a lot of arenas. However taking on that mentality fully strikes me as missing an important long-term perspective. I say this as a person who was really deficient in one digit's dexterity (pinkie) and instead of just kinda shrugging it off, I spent many years and sessions trying to bring it up to par. Now I'm happy to say I can really only remember it as a past weakness, due to the focus and attention to improvement!
You can either fix this by trying to copy what other people do in as many different ways as possible, or having a real expert around to say "No, try this instead."
Doing stuff over and over only helps if you're creatively blocked and are terrified of producing crap. It's a good first step towards building momentum, but it's just a beginning.
