You may not know what you ought to do next - but God does! And that's why the most important advice I can give you is to urge you to turn to Him and seek His will for your future.
You see, God knows all about you; after all, He made you. He knows your strengths and weaknesses, and He also knows where you will fit in. But He not only knows all about you - He also loves you, and He wants what is best for you. This is why you don't need to flounder around or take the path that seems easiest, because God wants to guide you to His path. The Bible's promise is for you: "Trust in the Lord with all your heart ... and he will make your paths straight" (Proverbs 3:5-6).
How can you find God's will? First, turn to Jesus Christ and ask Him to come into your life. He wants to make you part of His family, and He wants to guide you by His Spirit. Then ask Him to guide you as you examine your options; make your future a matter of constant prayer. Seek the advice of wise friends also, and be willing to accept new responsibilities and challenges.
In addition, let the Word of God, the Bible, be your guide. One reason God gave it to us was so we could know what kind of people He wants us to be. Put Christ first, and trust Him to guide you one step at a time.
