Highest and Best Use of My Life

This is one of those questions that I keep asking myself. I surely know that I'm wasting a huge amount of resources the main one being my soul. Not to mention my mind, my heart, my energy, my time. It' all just slipping through my fingers. Why do I go to a job I hate everyday, why do I live where I don't want to live, why, why, why? Year after year and soon those years will be use up and there won't be another tomorrow. The highest and best use of my life? I haven't a clue what that might be. I keep praying to God to show me to guide me, but I can't hear him yet.
