Quitting feels like shit. So does shitting. However, the difference between shitting and quitting is that when you’re shitting, you’re sitting, so it’s like a rest. Quitting is like hitting a filthy brick wall. Everything stops and you wonder Why did I start at all? Then you get up and you say Hey at least I don’t smell like shit. See, that’s the similarity between shitting and quitting: both of them involve letting go of waste, washing your hands (if you’re a decent human being), and moving on.
