I read the first chapter. The premise: dream 10X bigger than you currently do and produce 10X the work you currently do. Or substitute the word "others" for "you" in that sentence. We all dream too small and exert too little effort in pursuit of our goals.
Cardone denies following this 10X principle in achieving his own success. He also warns you might not achieve your goals--small or 10X--despite following this principle. Still, he tells you to succeed by following a system he hasn't tested himself and isn't convinced will lead to success. Is it a revelation that 10 times the effort and resources might lead to overwhelming success?
A flip through of the remaining 196 pages doesn't seem to offer much more substance.
Includes a 24-page Glossary of terms so basic it's insulting, though I give Cardone some credit for spending the most ink in his glossary defining Rotary Club.
