I've tried to listen his podcast, but i couldn't get into it. I don't know why. it's just puts me off. I don't think it's the content. The content was the main factor that made me check it out.
It's not the medium per se, although i space out a lot when i'm listening to something. But, i might being totally wrong, his podcast comes off as self-help voodo that comes from someone with a academic background.
