You drive the car, you don't carry it.
Racing is a passion...at this level, a source of immense gratification. So the rest is no problem.
There is very little in civilized life that demands everything you got intellectually, physically, and emotionally. Driving is living. It's aggressive instead of passive living.
Racing is a matter of spirit not strength.
Racing is a calling, a passion.
Let me ask you. If someone called you and offered you a ride in the Indianapolis 500 and you were a male race car driver, would you turn the ride down?
