Attention is genuinely finite, which makes every use of it a real expenditure with something given up in exchange. Treating it as free is why people end up having spent enormous quantities of it on things they would never have chosen to buy.

Price one of your regular attention habits in hours per month. Then ask what else that time could have been. The arithmetic is usually enough to change something without any additional resolve.
