“Many good opportunities are ruined for the dream of slightly better ones.

Would you be 10% happier in a different relationship? Maybe. Maybe not. But you'll definitely be unhappy in the one you have if you spend all day thinking about what else is out there.

The surefire way to end up worse off is to agonize over unchosen options and fail to make the most of the one you selected. Every minute spent yearning for your unlived lives is a moment you can't invest in the one you actually have.

And you have to do it no matter what is true. No matter what is hard. No matter what unjust, sad, sucky things befall you. Self-pity is a dead-end road. You make the choice to drive down it. It's up to you to decide to stay parked there or to turn around and drive out.”

“I strongly believe that the only way to encourage innovation is to give it to the young. The young have a great advantage in that they are ignorant.
