Go grab a folder (a real one, the manila kind) and label it “For Bad Days.” Stick it in the file drawer of your desk (or, if you’re one of those nomadic types, keep it in your computer bag).

Whenever you get one of those rare notes from someone expressing gratitude or giving you kudos, print it out and stick it in that folder. (I know, the poor trees… but keeping a digital file doesn’t work, at least for me.)

Whenever you’re having one of those imposter syndrome days when you wonder how anyone could possibly ever believe that you’re capable of doing your job, pull the folder out and read.

Replace the folder whenever tears compromise the integrity of the card stock.

Oh—and make a habit of sending the notes that will end up in someone else’s folder.
