The Strangest Secret

This is so good that I have listebned to it several times, shared it with my sons and my team

and now I decided to share it with you too.


“The Strangest Secret” is really not a secret at all.

In fact, the principles that it communicates are some of the same that I teach thorugh our Blackbelt Leadership program at Krav Maga Martial Arts.


But Earl Nightengale conveys this very important idea- The Strangest Secret- artistically in this 1956 recording by the same name…

so I have a challange for you.

Click the link above to listen to the recording, and then join Dani Tredway, Sensei Bryce, Sensei Thomas and I as we embark on the 30 day test that Mr. Nightengale invites us to at the end of the recording.


Let’s see what we can do.
