I don't know why people gave you that advice but it's pretty easy to tell when a designer hasn't spent enough (or any!) time defining their target market and then spending time with those people to listen instead of force fitting a technology. Without that up front work we're all just rolling the dice. That said, building stuff is fun by itself so it doesn't always need to be about money and growth. Just know it's a hobby.
