Touring is tough. You're almost in a haze because you don't really know where you are half the time: You're in a hotel room one moment, and the next thing you know, you're onstage performing for 60,000 people, then you're back on an airplane. It's very hectic and I couldn't do it without my family.
The human being is a self-propelled automaton entirely under the control of external influences. Willful and predetermined though they appear, his actions are governed not from within, but from without. He is like a float tossed about by the waves of a turbulent sea.
