The whole desiderata. It’s not as easy too remember as, keep calm and carry on. But I’ve found it to be a wonderful inspiration as a way to live life. Part of it is in my signature. The other motto I often repeat to myself is simply the word, KINDNESS. It reminds me to take a breath and try to see things from another POV before getting all bent out of shape.
A wonderful question, what motto do you live by?
