You can get your money back on almost anything. Nobody refunds an afternoon.

Money is reversible in a way time is not, and yet people guard the recoverable thing and spend the other without thinking. An hour given to something you did not choose is simply gone, with no receipt and no returns counter. That asymmetry should change how carefully you agree to things.

Before you say yes this week, ask what the time price is rather than the money price. Treat a long commitment the way you would treat a purchase you cannot return. And when something is genuinely worth your afternoon, give it the whole afternoon without flinching.
