Saved My Life

Lex is a great host who is able to book some very great minds, and they talk in depth about things that truly matter. And it keeps getting more interesting as time goes on… and on… I can’t wait to see what we are all talking about in 10 years time. It’s a fantastic show!

Brilliant Host and Guests

This is the best podcast, ever. Can’t believe it’s free. It covers so many interesting topics from many perspectives. This podcast gives me a few hours before sleep to focus on just one topic that interests me. I love how long they are. These aren’t conversations that can be had in 30 minutes. They’re deep interesting dives. I don’t like every guest but I always love listening to people out there working to understand the state of being, that will move us all into a better future, whether I agree with them 100% or not. Thank you for taking your time to make these podcasts, Lex.

The best podcast…

But let’s not talk politics. To entertain the left is to dance with the devil himself.
