It’s remarkably easy to point out how much of an idiot another person is, but how much of an idiot are you?
Each day, critique one thing that you do that’s stupid (use your own stupid calibrator here.) This is not so that you will dwell in self-loathing, but so that you can become aware of your flaws. This will then allow you to improve and be more accepting of the flaws of others.
You’re not perfect and neither am I.
