There once was a Bald Man who sat down after work on a hot summer's day. A Fly came up and kept buzzing about his bald pate, and stinging him from time to time. The Man aimed a blow at his little enemy, but - whack - his palm come on his own head instead; again the Fly tormented him, but this time the Man was wiser and said: YOU WILL ONLY INJURE YOURSELF IF YOU TAKE NOTICE OF DISPICABLE ENEMIES.
Hopefully with each thing that you do you're learning something, you're growing, and you're pushing yourself a little harder in some way or another. So I think you'd be in real trouble if each new thing that you create didn't feel like 'Oh, wow. I feel like I'm doing something a little different this time.'
