The material is in the title!!
I would not bother purchasing this audio book. If you google both "law of scarcity" and "social proof" you will find out more on these subjects in 5 minutes. Quite disappointed!!

Too soon to tell
I just got through listening to the audio book and quite frankly haven't put any to practice for a better proof of its effectiveness. However, the message resonates with me on a very high note. I am looking forward to listening to the entire book soon.
