What I regret most in my life are failures of kindness. Those moments when another human being was there, in front of me, suffering, and I responded... sensibly. Reservedly. Mildly.

Your life is going to be a gradual process of becoming kinder and more loving. Hurry up. Speed it along. Start right now.

Do all the other things, the ambitious things — travel, get rich, get famous, innovate, lead, fall in love — but as you do, to the extent that you can, err in the direction of kindness.
