Epictetus in The Art of Living:

My 10-year-old will still occasionally remind me of the time a few years ago when she saw me decline a stranger’s request for a couple of dollars. I was in a hurry and didn’t want to be bothered to fish around in my wallet for a guy on the street I would never see again.

My daughter was surprised, and clearly disappointed, I didn’t help the man. I regret the message that sent to her. I regret my failure to model generosity in front of her.

I have never regretted being too generous, though. When you consider an impulse to give, in money or service, see how it feels to up the ante, to offer even more than you think reasonable.

My wife is good like that. I will suggest a reasonable, safe gift, and she will trump it with an offer to do even more. And then I think, “Of course! Why not do better and give more if we can?”

Honor your impulses to do good, to give, and to be kind.
