You don't achieve anything by stopping at the first sign of difficulty. If we'd stopped after Dieppe in World War II, where would we be right now as a nation? If we'd stopped before Vimy Ridge, we wouldn't have been a nation at all. Yes, you've got to know when to say "stop" as a leader, you sure do, but you've also got to know when to push for the final thing that's going to give you the full benefit.
