I often wish I could go back to a time when my biggest fear and worry was making sure I passed that math test. Life was so much simpler then. But when I was a child this was enough to make me want to pull my hair out!
Now that I am an adult, I have learned that life itself is a series of tests. Some you will pass and others you will fail, for there is no text book from which you can study. No matter how well you prepare you will never get a perfect score, because mistakes will always be made. However, it is our duty to remember these errors in judgement and learn from them, lest we repeat them.
