Smart engineer/entrepreneurs #1 mistake is thinking that because they are competent in their field(or got good grates at an elite school) that somehow magically translates to competence in business and entrepreneurship. I know and have met quite a few people that are grinding away at or have made products which have serious business challenges that they underestimate or are blind to and predictably fail to overcome. It's kind of sad when you see a product that has taken a high degree of workmanship/skill/and effort to make, but which has no market. Or the flip side, which is an insufficiently differentiated(aka not better enough than what people are already using) product in highly competitive market.

You can say the same about artisans who have spent their lives perfecting their craft but don't know how to get the word out about their creations. So many labor in obscurity and their pieces are stunning.
