Testosterone is the hormone of collaboration and competition that, whenever we compete on a team, we collaborate with our teammates. And most of us in our daily life, to the extent that we have to compete with the rat race in the world out there, we're collaborating with other people at the same time. The two are hand in hand.

But I'd rather help than watch. I'd rather have a heart than a mind. I'd rather expose too much than too little. I'd rather say hello to strangers than be afraid of them. I would rather know all this about myself than have more money than I need. I'd rather have something to love than a way to impress you.

I used to want to change the world. Now I'm open to letting it change me.

Interests evolve into hobbies or volunteer work, which grow into passions. It takes time, more time than anyone imagines.

Allow for many paths to your goal. Do not fixate on one path, because then you are likely to give up when that path is blocked.

I can push myself and you can push yourself, but competing, we push ourselves a little farther and we bring out our best even if one of us wins and one of us loses. The virtue of competition is that we both get better, not that one does. And that means we have great respect for the opponents, whether we win or whether we lose.

The virtue of losing is we get used to the fact that competing and to lose doesn't kill you. It just makes you stronger. It just helps you get used to it.
