In fact, this is the EXACT way to go and succeed.
Instead of creating something and hoping that it will sell, identify a need and create a product that matches that need.
This requires some solid research and that's exactly what you want to focus on.
I know that this can sound like such an obvious basic concept and guess what?
Probably 80% of those who start something online get that one wrong.
They first start with their own need to share something.
That's THE MISTAKE.
Don't start from your own need! Start from an audiences need.
I know, sometimes those 2 ways of looking at it totally overlap.
But so often, what a potential audience actually want can actually be so incredibly different than products offered out there.
