You will learn lessons. You are enrolled in a full-time informal school called life. Each day in this school you will have the opportunity to learn what you most need to know. The lessons presented are often completely different from those you think you need. There are no mistakes, only lessons.
Growth is a process of trial and error, experimentation.
You learn as much from failure as you can from success. A lesson is repeated until learned. A lesson will be presented to you in various forms until you have learned it. Learning lessons does not end. There is no part of life that does not contain its lessons.
