If you ever get to a point where you feel useless, powerless, or worthless, think again. There are many in this world who need you and your voice. Even the young must realize that there are people (some not yet born) who will be looking to them to show them the way. Focus on the path God has set before you, and find your power in obedience and faithfulness, and you will grow strong. Use that strength to help the weak-- not to overpower them.
