Unfortunately this is bad advice for most people, because the truth is most people don't have the full skillset required to own a business. Maybe they could learn it if they apprenticed under an entrepreneur or in an executive role, but I'm honestly not sure.
I own a business with studios in New Orleans and Atlanta, but I worked in the real world, went to grad school, and then came out and immediately went out on my own which is easier for a lot of reasons.
I also think a series of fortunate and somewhat unreproduceable events led me here, strangely enough involving Gabe Newell, though I'm sure he wouldn't remember.
I honestly don't think reading a bunch of books telling you how to be an entrepreneur are helpful or real at all. In fact I would describe them as more of a stalling tactic.
