A life does not become valuable because everybody notices it.

Attention is distributed by visibility, timing, and luck, none of which have any relationship to worth. Plenty of valuable lives are unwitnessed, and plenty of witnessed ones are not much. Treating notice as the measure means outsourcing your evaluation to a process that is not evaluating anything.

Ask what you would still consider worth doing if nobody ever knew you did it. That question tends to separate what you value from what you have been performing.
