About this quote

Most people run this backwards, magnifying others' failings and quietly excusing their own. Flipping the lens means holding yourself to the strict reading and giving other people the generous one. It's less about humility for show than about getting an honest measure of who actually owes what.

When to use it

  • After a shouting match, a wife asks first what she got wrong before tallying her husband's part.
  • A manager reviewing a failed project scrutinizes her own calls closely and reads her team's slips charitably.
  • When a friendship cools, a man wonders how he contributed instead of listing every way his friend let him down.
