But here's the rub. You will never do anything with that brilliant efficiency save what you LIKE TO DO. Efficiency does not come from duty, or necessity, or goading, or lashing, or anything under heaven save ENJOYMENT OF THE THING ITSELF. Nothing less will ever release those hidden powers, those miraculous forces which, for the lack of a better name, we call "genius."

I've said it before, and I'll say it again. When you find something at which you have talent, you do that thing (what ever it is) until your fingers bleed or your eyes pop out of your head.

Do it for joy and you can do it forever.
