Don't sit on creative ideas waiting for the skills to apply them. The ideas you come up with developing those skills will be so much better, and you'll have a lot of noob stuff to look on fondly. Applying the noob ideas is how you get there. I see too many writers, musicians, etc holding on to some idea they've always wanted to work on until they somehow develop the skills with ideas they don't, so they never do anything.

And then they finally get to it, work through it, look back years later, and realize the idea they sat on was far below what they were capable of once they finally worked through it.
