We are here to learn lessons. That is what life is about. Each day we will have the opportunity to learn lessons. You may like the lessons or you may think them stupid or irrelevant. There are no mistakes, only lessons.
Growth is a process of trial and error experimentation.
The experiences that we label failures are as valuable a part of the process as the experiments that ultimately work. A lesson is repeated until it is learned. A lesson will be presented to you in various forms until you have learned it. When you have completely learned a lesson, you will then go on to the next one. Learning lessons does not end.
