“Wherever you are still inept, wherever you are still lacking, that’s where you must apply yourself. If you haven’t yet cracked it don’t give up. Having finished with one thing you get stuck on another, so persist with it until you crack it, don’t let up. Don’t be content until it’s finished. Put all your attention on that point. While sitting, lying down or walking, watch right there.”
~Ajahn Chah (from “Food for the Heart,” pp. 94-95)
