No one is equal to the market.
Products like this There's no way they'll sell." means, "I won't buy them even if they're cheap." And I don't know the difference between myself and the market. This product It will definitely sell." means "I will buy it if it is cheap." And I don't know the difference between myself and the market. Especially creator should be careful. Even if the creator thinks, "This is a good product and should sell well," it does not necessarily mean that the market will think it is a good product.
Even if the creator thinks, "This kind of product will not sell," it may sell surprisingly well.
By assuming on their own that they will not sell and avoiding testing the market, they lose the opportunity to correct their assumptions. 2019-03-01
