What is your heart's desire? If you truly desire to do something for God then I don't believe you will be disappointed. Warning here. If you try to make it happen or compromise in any way to get what you want, it will never happen with peace. It will come with a price that will be way more than you could ever imagine. It will take God to fix a problem that should have never occurred. If you are there? Repent. Tell God you are sorry. Ask Him to get you back on track. He is faithful to forgive and restore.
ACTION STEP: Live ready. By this I mean live a life filled with the faith that comes from reading and hearing the word of God. Get in a good church where the Word of God is preached. Do what is asked of you no matter how insignificant you might think it to be. God prepares before he promotes. God makes the man/woman before He sets them in position. He fills a vessel before He pours it out. Get ready. Live ready, set, go! God is with you wherever you go.
