I am reminded of a phrase from a friend/colleague.

"If you don't know the difference between good advice and bad advice then no advice will help".

In my work as a CEO Peer Group Faciitator we have a rule that each member was forbidden to give advice that they were not competent to give. Can you imagine

how much conversation/noise that eliminated?

How would you lead your life if there were no "gurus" to tell you?

What is to be learned from this story if Ferriss cashes in on a top ten podcast? Are we stupid or what?

How about giving back all the $ that was essentially stolen from all those who he grifted.... with his advice?
