We create casual equivalencies between volunteering and our level of commitment. We think that because we raised our hand to help out we can raise our hand to opt out at the inconvenient moments. This is how our fine and noble intentions degrade into good enough outcomes. This is how our integrity gets compromised. Integrity is an all-or-nothing virtue (like being half pregnant, there’s no such thing as semi-integrity). We need to display it in whatever obligations we’ve made.
