Life is a teacher. In life you will go through all kinds of teachings, but it is the none that you learn from, which is going to make the difference. There is nothing about life that will change without your cooperation. If you want to see the difference in life you are the only one that can make the difference. The lesson is what you learn and the test is what you will pass, which will make the difference in your life. What you will apply will be your evidence.
