How many times have you asked the question "what am I doing here?" Grandpa's answer is interesting and thought provoking. Whether or not you agree with his answer, he gives us a lot to think about. He believes everyone needs to answer the question or else they will be manipulated by others as they go through life. Being manipulated by others is not a happy place. The train ride of life moves rapidly down the tracks and it seems to be moving so fast that you can't get off, if and when you realize you should. Answer his question and you can control which train to ride and get on and off the train ride when you want to, not when someone else tells you to.
