Even if you are only moderately good, you'll have a unique combination of knowledge that allows you to see things that others can't, and that will enable you to do amazing things.
Of course you should always try to improve. But consider where you invest your time. If you know X well, and most people that know X well also know Y well; then maybe you should learn Z instead of Y. Don't always choose Z -- maybe X and Y are complementary and so it may make more sense to learn Y than Z -- but if you follow someone else's curriculum exactly, you will only be re-discovering what they already know.
I don't think of it that way, at all.
