When choosing a niche that fits you, you should be choosing something that is ideally an interest, a passion, a hobby, but it could be something that you would like to learn about. You don't need to BE an expert, you BECOME an expert.

I personally enjoy many different things. I enjoy basketball, I used to collect baseball cards, I like to go skiing, I am really interested in men's fashion, exercise, internet marketing, and I love everything about the online business world.
