Affiliates Course or Niche Course?

Still doing the 10 day Master Affiliates course and getting quite a bit out of it.

There is 1 thing that is slowing me down and that is finding a niche. I have done some research on a few niches but have yet to come up with anything that seems like it would be overly profitable.

You would think that this would be the easy part but I seem to be having a hard time with it.

I'm interested in so many things but to actually become the expert in that field, well that's a different story.

My list contains certain books, authors and characters. Also gadgets and technologies of which would be very hard to pass as an expert but also so much competition.

Also sports of which motorcycles are high on my list. Moto gp for example = competition.

I work in hospitality so was looking for something in there but nothing yet. I'm sure there is a need for a high end hospitality site who refers different top class hotels but then there is so many to choose from, how to narrow that niche down?

If you have any ideas for me then pass a comment on to me and I'll do some research to see how it looks.

I really think that being an affiliate is the way to go and just this small step is seeming like it will never reveal itself to me.

Take care
