“But talent only functions when it’s supported by a tough, unyielding physical and mental focus. All it takes is one screw in your brain to come loose and fall off, or some connection in your body to break down, and your concentration vanishes, like the dew at dawn. A simple toothache, or stiff shoulders, and you can’t play the piano well. It’s true. I’ve actually experienced it. A single cavity, one aching shoulder, and the beautiful vision and sound I hoped to convey goes out the window. The human body’s that fragile. It’s a complex system that can be damaged by something very trivial, and in most cases once it’s damaged, it can’t easily be restored. A cavity or stiff shoulder you can get over, but there are a lot of things you can’t get past. If talent’s the foundation you rely on, and yet it’s so unreliable that you have no idea what’s going to happen to it the next minute, what meaning does it have?”
