Do not let a passing comparison choose a commitment you must carry for years.

A moment of comparison lasts about an hour and the decision it produces can last a decade. Someone’s kitchen, someone’s job title, a photograph of a life that looked easier: while the feeling is sharp the mind builds a case for the mortgage, the course, the move. The commitment does not fade on the same schedule, and afterward it is hard to remember why it seemed urgent.

When a comparison arrives, notice it and then wait a fortnight before doing anything about it. Ask whether you would still want the thing if nobody knew you had it. That question separates a want from a reaction better than reasoning does.
