A good question to ask yourself when you find that one person doing just that.
Honesty and taking ownership over what you do to other people is a rare trait. Try it once in a while. I yields amazing results.
Remember: the fanfare isn’t the reason you are doing things. You do them because by putting forth the positive into the universe, you know that it will come back to you someday – when you need it most. Carry out a random act of kindess knowing it will come back. Don’t look for a pat on the back. Sit silently in that knowledge that love and kindness begets love and kindness.
