Remembering you won’t be here forever is the best focus tool there is. It makes small stuff feel small.

Awareness of an ending sorts things by size very quickly. Petty irritations, minor standing, the argument about nothing, all of it loses weight against the fact of a limited stretch, and what stays standing tends to be people and work you actually care about. Used lightly, this is clarifying rather than frightening.

Bring the thought in for a minute when you are stuck on something trivial, then put it down again. Ask whether this would make the list of things that mattered. Most of the time the honest answer settles the problem for you.
