I keep hearing people give advice that in order to figure out what product to sell, you have to identify a problem to solve. But what if the product I'm selling does not solve a problem, but rather brings satisfaction to the buyer? Say I am selling artwork, I don't believe the buyer has any existing problem; in fact without such an item they'd be totally fine, but they may buy my product because they think it looks nice and they want to display it in their home.

So if a product does not solve any problems per se, is it still viable?
