It’s really important to forgive yourself. A lot of teachers set very high standards for themselves. It’s easy to get down on yourself if a lesson didn’t go as planned or you didn’t stop by the store to pick up the items for a class project, and you have to delay the activity. If this happened to your cohort, you’d try to make them feel better, because in the grand scheme of things, it’s not that important. Do the same for yourself!
