A wise man gets more from his enemies than a fool from his friends.

Mi parte favorita de la película Rush:

Niki Lauda: You know in hospital the toughest part of my treatment was the vacuum, pumping the shit out of my lungs. It was hell. And when I was doing it I was watching television, you winning all my points.

James Hunt: Your points?

Niki Lauda: That bastard hand, I would say. I hated that. And then one day the doctor came and said, “Mr. Lauda, may I offer a piece of advice?” Stop thinking of it as a curse to have been given an enemy in life, it can be a blessing too. “A wise man gets more from his enemies than a fool from his friends.” And you know what? He was right. Now look at us. We were both a pair of kids when we met. Hot headed jerks in Formula Three. Disowned by our families, headed nowhere. And now we’re both champions of the world. You pushed me that far and it felt great. I admit it, I was prepared to die to beat you that day. And that’s the effect you have on me. It’s not bad, huh?

Quiero tener un enemigo como Niki Lauda.
