Agree with pretty much all that has been said previously. Though, I'd like to add one point to the 10k hours topic.
These hours are not just 10k hours spent on doing the same thing over and over, having same results as after 100 (or whatever) hours. I think he stressed this in his books as well, that it is actually deliberate practice. And if you don't know how to improve all the time, then you'd need some outside guidance. You can spend all these 10 years cutting scrolls that look like crap both technically and design wise, you've spent your time, but you're still no good...
