I'm insatiably curious about human nature.

Opposites attract, and I think temperament is so fundamental that you end up craving someone of the opposite temperament to complete you.

When you're more focused in getting your message across than you are worrying about how people are viewing you, that's huge.

I worry that there are people who are put in positions of authority because they're good talkers, but they don't have good ideas. It's so easy to confuse schmoozing ability with talent. Someone seems like a good presenter, easy to get along with, and those traits are rewarded. Well, why is that? They're valuable traits, but we put too much of a premium on presenting and not enough on substance and critical thinking.

The other thing Aron found about sensitive people is that sometimes they're highly empathic. It's as if they have thinner boundaries separating them from other people's emotions and from the tragedies and cruelties of the world. They tend to have unusually strong consciences. ... they're acutely aware of the consequences of a lapse in their own behavior.

You're told that you're in your head too much, a phrase that's often deployed against the quiet and cerebral. Or maybe there's another word for such people: thinkers.

Indeed, your biggest challenge may be to fully harness your strengths. You may be so busy trying to appear like a zestful, reward-sensitive extrovert that you undervalue your own talents, or feel underestimated by those around you. But when you’re focused on a project that you care about, you probably find that your energy is boundless.
