Wow, now that's an old book by a real guy who could breadboard TTL chips into the equivalent of a graphics card at that time. Sort of another Wozniak, though that kind of bare metal knowledge was expected of all EE's.

What he has to say is not compatible with the current pop culture "startup" hype but it's still valid.

One thing also mentioned is correct: when you're in business, sometimes you get more than you expected, just for showing up. That very rarely happens in a regular "job."
