You can buy a nicer watch. You can’t buy one more minute. Spend accordingly.

Money can replace most things and not the one thing it usually gets spent chasing. A better version of an object is always available, which makes buying feel like progress, while the hours that went into earning it are the only genuinely finite resource you hold. That trade stays invisible because time carries no price tag.

Work out what an hour of your pay actually buys and divide the next thing you want by that number. Ask whether the object is worth that many shifts. Sometimes it will be, and sometimes you will put the hours somewhere that cannot be replaced.
