to add to C, unless he's a terminal case of the OP image, he doesn't need actual life-or-death stuff, but he does need *discipline*. he needs to be put into (put himself into) situations where he needs to man up and focus or something goes completely tits up and he loses very valuable things.
i find that having to work outside in adverse weather has given me immense perspective on what discipline means. on my farm in the first years before we reinforced everything against the weather it was always a mad dash to save things before pouring rain or gale winds destroyed them, and it taught me a lot about doing things even when they're uncomfortable and when you'd rather be doing anything else. hell, you actually learn to feel at peace while enduring discomfort, it felt very masculine in a raw sense.
once you get used to it, it becomes almost trivial to apply to day to day things that also need discipline, like chores or long-form hobby projects.
B) turn off all the screens. All of them.
C) do things that require your complete focus or you die. Like high speed driving or power tools.
My brain is fried from screen use. I will work on cutting down on screen time.
