Don’t expect payback. There’s far too much of the “favor forward” nonsense where we expect some act in return for our own kindness. Don’t provide a kindness that’s conditional, awaiting some acknowledgment. Simply provide help for the joy of having done so without a quid pro quo.
Mindset: It’s senseless to allow a driver to turn in front of you and then become upset when you’re not thanked! You’re most when you can do good things without have to be acknowledged for them.
