If you do Spotify, his "Discipline Equals Freedom Field Manual" is on there for free (or as free as Spotify is anyway): https://open.spotify.com/album/3VHxlMnG9PDcXyzWrITCf6?si=M-_UmF-5ReG-2T_nFG5laQ

I'm not going to claim he has any magic insights, but sometimes his stuff hits just right to give you a good kick in the pants.
