1. Examine your impressions. “So make a practice at once of saying to every strong impression: ‘An impression is all you are, not the source of the impression.’ Then test and assess it with your criteria, but one primarily: ask, ‘Is this something that is, or is not, in my control?’ And if it’s not one of the things that you control, be ready with the reaction, ‘Then it’s none of my concern.’”
