Get to know God. I mean to REALLY know Him like your best friend! He knows why He made you and can help you find your purpose better than you can find it on your own. Take it from one who lived 40 years before finding my own best purpose to live.
Get a Job, Go visit a place you have always wanted to, Jump from a plane, bungee jump, um idk rock climb idk what you have already done. Think of your most favorite things and go do it. Go to the Olympics.
