The bus you chased and missed is gone. The next one is already on its way, and you’re out of breath for nothing.

The chasing happens after the thing is already gone, which is what makes it expensive. Nothing about the sprint changes the timetable, so all of it is spent on a past that is finished, and you arrive at the stop worse off than if you had walked. Regret runs on the same mechanism.

Give the next ten minutes to the next one instead of the last one. Look up the following departure, send the next application, ask the next person. Being out of breath over something already settled is the only part of this you actually control.
