How you take care of it or fail to take care of it can make an enormous difference in the quality of your life. You will learn lessons. You are enrolled in a full-time, informal school called life. Each day, you will be presented with opportunities to learn what you need to know. There are no mistakes, only lessons.
Growth is a process of trial, error and experimentation.
You can learn as much from failure as you can from success. Learning lessons does not end. There is no stage of life that does not contain some lessons. As long as you live there will be something more to learn. Others are merely mirrors of you.
