I do love the Warrior Poet concept, but I'm going to say what we've all been thinking—Paul P. looks like he was carved out of granite. He and I share the white beard color and crow's feet, but I really look up to him—NOT a tasteless joke—about how fit us old dudes can get.
I can honestly say that quitting (crappy) carbs and sticking to a fasting plan has been the fight of my life. Quitting smoking and drinking both were much easier for me. Over the course of a career in management, I went from being a tradesman to a dude that parked at a desk all the time, even when I could've gotten out and walked around some. Now I work from home, and I'm forced to acknowledge that I have a discipline problem. I am doing the work on eating correctly, hitting the elliptical, and lifting; though I have found myself dusting off and getting back on the horse more times than I want to admit.
And while I'm working on the discipline, and I know we need it over "motivation", I find the thought of becoming another Battle Gnome a powerful inspiration.
