Hey mate, I've been meaning to reply to this one for a couple of days. Only just got around to it. I've listened to Jocko and Echo Charles on their podcast for a while now. So many good lessons to learn. How intense is Jocko man? I listen to them more from a leadership and military perspective but get a lot out of the BJJ chat as well. Discipline, control etc. Good on you for getting amongst it.
I hope you have a great 2018 planned. All the best.
Jocko is the man. I do enjoy his podcast, although I usually just catch highlights here and there. If you haven't already, you gotta check out Discipline Equals Freedom - the audiobook is best. I also listened to Extreme Ownership which is amazing and has heaps of great stories from the battle of Ramadi.
