“When we pillow our heads at night, we need to have things that give us peace. Many such things are available, but one of the best is the simple peace of knowing that we've done things that day that were not easy for us to do. If we can see ourselves as people who are learning little by little to master the hard parts of life, we will live with a greater confidence and be able to serve those around us more helpfully. The ancient adage is true which tells us, "A ship in the harbor is safe, but that is not what ships are built for.”
