“I have packed a bunch of failed startups in the past and I would drive my mind crazy I would spend a year building a product that nobody would ever want and so now my marketing is mostly launching and I see how people react”

Real traction means go all-in; a couple hundred bucks at launch with no excitement means keep it running and move on — never spend another six months on something probably nobody wants.
