Don't get discouraged. I also have days when I think that my niche is too broad. I've been able to narrow it down a bit after I started to add more content, so I think you'll be able to find a way as well; don't give up. =)

Hi There,
Well, you are not alone, we all traveled that road, and mind you, I am still sorting, plucking and trying to fit a niche in the global world of products.

I must say, please don't get discouraged. You cannot to compete in this market, as you said it id too huge, and the competition is great and growing my the thousand.

Now, i reall like what you said, about narrowing your niche down. I think that is the best route to take with any given product. Again, i must say that, you are in a great area, just don't focus on other's out ther, just look at it like this, YOU ARE THE ONLY ONE Own THIS Planet.

Now start grounding it down, do some research, and be different, so your niche stands out amongst the majority.

Something odd, a passion, something they need.

Okay! have a great Week!
