I’ve grown suspicious of the inspirational. It’s overrated. I suspect duty — that half-forgotten word — may be more related to happiness than we think. Want to be happy? Mow the lawn. Collect the dead leaves. Paint the room. Do the dishes. Get a job. Labor until fatigue is in your very bones. Persist day after day. Be stoical. Never whine. Think less about the why of what you do than getting it done.
