"All growth depends upon activity. There is no development physically or intellectually without effort, and effort means work."
- Calvin Coolidge
I think that's the tricky little point that trips up and derails creative people. The have dreams, goals and the drive to accomplish them, but don't have the focus to put that drive and ambition where it needs to be. Instead, they spread themselves too thin bay doing anything and everything all at once.
Working hard to grow it how thing get done and improvement happens. Working hard with laser precision focus is how you grow faster, bigger and more importantly sustained.
