Before you build a product, build your demand.
You can check out existing demands in the market or you can make your own demand.
If your product is build before demand, nobody will buy it.
You want to be sure that the market will pay for your product.
You can create a product for everybody, or you can niche it down to a certain degree.
Always invest money in your own business because the business will make you money – someday.
Building a demand on a personal brand takes very long, there are sure easier businesses.
Also, don’t pretend to be a pro if you are not a pro. Because the pros will see your knowledge lack.
