Why is finding a niche so tough?
I know, I know...we all want to start out in the "perfect" niche. It just doesn't work this way and who in specific defines what the perfect niche is.
Is this something that is defined by some "niche guru" out there that knows something that you don't about whether or not you are going to make a niche profitable? No.
ANY niche can be profitable, because you make it profitable!
I have created a video that will walk you through the process of "How to Find a Profitable Niche".
The more interested you are in a niche and the easier it is for your to create content, talk about, and research a niche (because you enjoy it), the more successful you would become.
Would I enter the "model air plane" niche simply because it was profitable? No, because I don't know the first thing about them and frankly I have no interest in writing about, talking about, or creating a business around this niche. If you love them though, this could be your niche.
Choose something you enjoy and that something can and will become profitable with some effort.
