The book is tremendously rich in ideas on how to make things happen. Find some useful advice on how to improve your life. The only caveat is that it invariably takes some mixture of chutzpah and hard work. He has some great advice on how to hack the business of making contacts. How to crash conferences, college courses, and other gatherings of people who are likely to be helpful to you. He tells you how to hack emails - how to get in touch with people who can be useful to you, and how to write an email that will get an answer. He made me feel good. I sent him a cold email asking for a copy of this book to review, and this is the result. Useful for both of us, the way things should be.
