On Discipline

Atul Gawande in the The Checklist Manifesto:

Discipline is hard — harder than trustworthiness and skill and perhaps even selflessness. We are by nature flawed and inconstant creatures. We can’t even keep from snacking in between meals. We are not built for discipline. We are built for novelty and excitement, not for careful attention to detail. Discipline is something we have to work at.
