I am rowing in a kayak on a cloudy day. I feel tired, humiliated and discouraged. The other rowers can't believe how bad I am. In a moment alone, my trainer, Barack Obama, approaches me in his grey-blue track suit, puts one of his sneakers on my kayak and his hand on my shoulder. He gives me a good pep talk about determination and not backing down. He also says, You shouldn't even be this tired, and gives me proper rowing techniques. Then I feel better. Even if I am going to lose that day, I at least have the sense that I had tried my best.
