quote post from 11 years ago
"Convincing yourself that what you did was good enough, when you could have tried harder. Pushing at what I’d call the “molecular level” – that last microscopic bit of effort, trying so hard to make your fingers stay on a hold that if you fail it is for absolutely mechanical reasons. Giving up at the finer level is still giving up. It keeps us from reaching our highest potential."

The quote is about climbing, but true in our context too.
