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.

Curiosity is a raw and genuine sign from deep inside our tangled psyches, and we'd do well to follow the direction it points us in.

That's a crucial competitive skill.
