I recently had the chance to come up with a mission and vision for my life. More information on what it is will be below this article. A life without a specific mission, is a life wasted. I am a changed person because I have a mission/vision for my life. I no longer waste time doing what I am not called to do. With a lot of prayer and reading of the Word you can come up with your own statement. Blessings!
