But I see the core message as something else altogether: In pretty much any area of human endeavor, people have a tremendous capacity to improve their performance, as long as they train in the right way. If you practice something for a few hundred hours, you will almost certainly see great improvement—think of what two hundred hours of practice brought Steve Faloon—but you have only scratched the surface. You can keep going and going and going, getting better and better and better. How much you improve is up to you.
