Seriously, who are these people who believe that sales alone can fix everything or building a great product alone can change their life? Everyone, and I mean literally every human being I have interacted with on this topic have assured me of the difficulty, complexity, and multifaceted-ness, of what it takes to get something going from ideation to profit, either through their fear of stepping into this territory of entrepreneurship or through their experience. And anyone who has been an entrepreneur or at least has tested the water will definitely have some sort of intuition for what it takes. If people still rely on a single factor, either they are one of those fraudulent aholes or the asocial nerds who should improve their sales skills(or hire someone who has the required skills). Never understood people taking about the multivariate and complex nature of life. It is complex and multivariate; and everyone knows it.
