I definitely don't think Jocko's material on "how to get things done" is his strongest suit, and I don't think he intends it to be really.
I would say that temptations do disappear if you successfully implement a mindset of "it's really not an option", but again, the implementation of that mindset in the first place is tricky.
Honestly I think one of the benefits of being in the military, at least for a certain type of person, is that the military provides a supporting framework and incentive structure for building good habits. You work out every day because it's part of your job, basically. You put yourself through all kinds of physical deprivation because you have to, it's required, you're not making yourself do it, you're being ordered to do it. For the same reason, professional athletes don't have to badger themselves to go to the gym -- going to the gym is aligned with their other goals. For people like me, going to the gym is a distraction from my other goals.
I've recently been extracting extraordinary value from the Jocko Podcast.
Jocko Willink is a retired Navy SEAL commander, jiu-jitsu black belt, management consultant and, in my opinion, master rationalist. His podcast typically consists of detailed analysis of some book on military history or strategy followed by a hands-on Q&A session. Last week's episode (#38) was particularly good and if you want to just dive in, I would start there.
As a sales pitch, I'll briefly describe some of his recurring talking points:
The Q&A sessions, in which he answers questions asked by his fans on Twitter, tend to be very valuable. It's one thing to read the bullet points above, nod your head and say, "That sounds good." It's another to have Jocko walk through the tactical implementation of this ideas in a wide variety of daily situations, ranging from parenting difficulties to office misunderstandings.
For a taste of Jocko, maybe start with his appearance on the Tim Ferriss podcast or the Sam Harris podcast.
