“If you don’t own the goal and it doesn’t come from your dream, then you won’t have the toughness to persevere when the going gets tough. And I will promise you that the going will get tough. There is never an exception—everyone who wins must push through obstacles, lots of them. You simply will not get up at dawn for your three-mile run because your wife wants you thinner. Big goals require big backbone—wimps need not apply.”
