Written in a story format (it is a compilation of events and observations), this book explains the several methods of influencing people, how to identify influence tactics, and how to safeguard yourself from them.
The 10X Rule
Written by Grant Cardone, the 10X Rule states that to achieve anything great, you need to put in 10 times the effort. A great motivator for massive action. The style of the book is pleasant to read.
