I think one of the underrated things that Bryan does is he regularly emphasises how central sleep needs to be in your health. I haven't heard that consistant message drilled in by anyone else and it helped me realise how a lot of the things i found difficult to recruit energy/discipline/motivation were related to the low priority I placed on sleep.

Peter Attia is also big on sleep. But it sits alongside 3-4 other things of similar importance in his messaging.
