???? HELP ???

I have a small knowledge of what i want my topic about. I have narrowed it down to between 3 different things that i really enjoy, and within those subjects are a few subtopics that i might try to pair up with them. It's somewhere between sports which would be basketball or football. It could be about cars or driving. The last thing it could be about helping out at anything. I know that's too broad of a topic but I haven't quite narrowed it down yet. As you see I'm still very undecided. Hopefully I will figure out what i want to do and do it soon!
