Many gurus while promoting their courses or ebooks like to show a screen shot of their earnings for example, Amazon Report Totals for June to convince potential customers that what they teach works.
I have 2 questions here.
First, can those Amazon Earnings Report Totals be trusted? Could they fake them if they wanted to?
Second, do sincere, honest gurus exist? Is it possible to have gurus who don't hold anything back and go all out unselfishly to teach all they know?
Reason why I ask this question is, if they are already earning so much money, why would they want to sell what they know for less than $100, why don't they just keep to themselves what they know and earn all the money they possibly could and enjoy their life to the fullest? Why do they want to teach?
Look forward to any feebacks from anyone because I don't want to be cheated.
