When I was graduated high school, my parents presented me with a tiny green pocket version of "Don't Sweat the Small Stuff for Graduates." I read through it all in a hour (it is a small book) and several times again over the following weeks and months. It had a lot of good pieces of advice in there. But as years have passed and I lost my copy in moving, I can only remember piece of advice because it resonated with me so much at the time.
