The usual, hire people that do the work for you and create things that keep earning money in perpetuity, cliches on how to make more money, have more free time and be more productive.
As someone that owned a business for years and made good money, I can personally attest that some of us no matter how hard we work or how many books we read will never be good at managing people and will never have those magical skills that enable us to hire those people that let us move on with the other things in our lives.
That is the skill I simply am convinced you are either born with or not and people that have this skill never understand how to teach it to those of us that do not.
I did enjoy the sincerity of the author and though he may not be covering new ground he covers issues that are worth reading about again.
Even if you do not usually enjoy these type books, read just the epilogue, especially if you can get the book for free as that is, by far, what I enjoyed the most.
The next best thing about the book may be its cover, probably the reason I read it. Kudos to the author for understanding the importance of a catchy cover.
