I found this book especially insightful.
FollowSteph3 reminds me a little of Mike from the podcast. While Rob Walling realizes he needs to hire freelancers etc. in order to sustain the business and make it work in a reasonable time frame, Mike took a few solid years to bring in other people. He wanted to do it all by itself. I've been listening to the podcast for a few years and you can see how Rob built one solid business and just launched another one in the same time frame Mike barely did one.
