My experience is the number one strength a founder has their passion. It's really not something that can easily be copied and given the vast amounts of opportunities in the world, hiring someone that really knows how to map that passion to a business model and attack the assumption has zero to do with being an entrepreneur, it's just another skill. Core issue is if the founder is not learning from the process and owning it.

Anyway, it's a topic that's interesting to me given how bad most startups are at it.
