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.
According to me, your life is going to be a gradual process of becoming kinder and more loving. Hurry up. Speed it along. Start right now.
Success is like a mountain that keeps growing ahead of you as you hike it... Err in the direction of kindness.
Do all the other things, the ambitious things - travel, get rich, get famous, innovate, lead, fall in love, make and lose fortunes...but as you do, to the extent that you can, err in the direction of kindness.
