I've been in a poor physical shape many times in my career and I've had some of my best results. My best performances happened because my mind was in the right place. The mind is definitely stronger than the body.
My dad, as a guy, had to quit school in the ninth grade, fought in the Battle of the Bulge. And spent his life pushing wheel barrels of heavy wet cement. So we've gone from pushing cement to now in one generation pushing legislation. But we always want any president to succeed, to do well; that means America does well and Americans do well.
