I happened to find this great post written by my cousin's cousin on honing your craft. She is a talented musician, but what she says easily applies to any creative endeavor. If you want to be really good at something, you have to practice it obsessively. She describes learning techniques for playing the piano well, but I was reminded of making chainmaille. Any time a student of mine tells me that she would like to have better closures, I reply that if she wants really good closures, she should make a piece of clothing. Closing 10,000, 15,000, or 30,000 jump rings will help you hone your skill (if you don't tear your hair out first, of course).
In any case, the blog post is a good read for anyone who wants to know how someone creative develops their skill. Read her blog post here.
