Who Do They Think They Are, God?

Biggest lesson is if they don't pay your bills, sustain your ability to work via health rituals only you can do, feed your family, fund your start-up, sleep/eat well/exercise on your behalf: they have no business telling you how to spend your time/energy or getting in the way.

Find self-care that is fulfilling to you. The extra mile is worth the long-term health restorative effects of investing in yourself for mental health (around your obligations/child/dependents), but otherwise, your time/money accounting isn't something just anybody needs to "get."
