"Seek critical feedback, ask [friends] what’s wrong. You often have to draw it out in a nuanced way because friends don’t want to tell you exactly what’s wrong because they don’t want to hurt your feelings, but they often know. So that can be really helpful. And then you keep trying to make it better and better. And then if your product/service is sufficiently better than whatever else is out there, or if there’s nothing else like it, then your company will succeed."
