First off, whoever decided to name these concepts Man 1, Man 2, Man 3 and Man 4, FUCK YOU! You've made it basically impossible to google that shit and the names do nothing to clue in the uninitiated. Couldn't you have just named them The Physical Being, The Emotional Being, The Cognitive Being, and The World? Look it's easy to be informative and not gender centric. I'm not apologizing for it. Fuck You!
Anyway, from the context of the conversation the other night it sounded like there was this concept of Man 4 being some super meta state of being where you just control the other three Physical Emotional and Cognitive beings, to which I also say, Fuck You! That's Bollox! Man 4 is the actual shit that you have limited control over that constrains and shapes your behaviors. The Cognitive being can try to go deliberately against The World, but they will fail in the long run. You can push water up the hill all you want, but you aren't going to change the flow unless you move The Dirt, aka The World, the so called Man 4. Punch that Sucker where it counts, move The Dirt. And yes, you can do this with the other three parts of yourself, but that doesn't make you The World or Man 4.
Some examples of moving The Dirt.
Taking a different shift at work
Getting a different job
Investing in a passive revenue stream
Changing what you are subscribed to online
Unplugging your Router
Changing where you hang out
Establishing or severing ties with friends/acquaintances/family members
Scheduling and performing tasks until they become habits
Re arranging your space
Learning new information and changing your rationality
An example of not moving The Dirt.
Looking back at your week on Saturday night, having not changed anything, remembering that you had a goal to exercise more, shrugging, sighing, saying you'll try again next week, and not cancelling plans or making plans for the next week, leaving the trough untouched and watching yourself flow through the same sequence of rational decisions and justifications you flow down every week till the next Saturday night.
The Dirt often moves without explicit intention, just like a river will change it's course gradually from one year to another. Sometimes other friends and family will have something change in their life and they can no longer make it to that weekly meeting that sustained your relationship with them. Sometimes you get fired from your job. The World shifts indifferently and sends you down paths that if you aren't careful, or aware, could end you in a lonely, constricted, powerless place. But you can move The Dirt intentionally. This is hard work because there is uncertainty and there are consequences you can't anticipate. And you have to face up to those consequences. This is an art and not a science, there will be tradeoffs that you won't notice unless you are looking for them, the outcome will be uncertain the first few times you try, but do it enough and you might start to get the sense of how to get that stream where you want it to go and how to mitigate the tradeoffs...
That said, just like manipulating a flow of water in real life, it is entirely possible to really fuck up someone else's existence if you aren't careful. "Oops, I just re-directed this river and washed away your house" is entirely possible. "I just invested in a passive revenue stream" and "you just got priced out of every living space within miles of where you've lived all your life" can be a lot closer than you might realize. And the same could be said of your own existence, "I'm going to start taking a drug that is socially stigmatized" can quickly become "I'm hiding this habit from friends and family and bailing the waters of shame" if you aren't keen on how shit works in the world. Or how about this one, "I've started attending Positive Outlook courses so I can learn how to manifest a better future" can quickly become "I've been sold a bill of goods, I'm out a lot of money, and I still don't know how to change my life." How about this one from my actual life. "I took a job that more aligns with the skills I went to school to obtain because It pays noticeably more than my last position." Led to "I now have hours of time at work with little to no work to occupy me, and I'm barred from the usual sources I turn to in order to stave off boredom. I have to adapt to this situation carefully or I could develop severe mental health issues or a financially ruinous impulse buying problem."
There is no magic here. Using these methods probably won't solve all your problems. You aren't likely to become amazingly rich or become a totally different social being getting laid every night in the blink of an eye. But it will probably get you out of a rut and give you experience. So yeah... If you aren't doing what you feel you should be doing, Start moving The Dirt, start somewhere small, move your alarm clock across the room so you can't punch snooze without getting out of bed, punch man 4 where it counts, see what tradeoffs emerge, rinse and repeat till you die cause once you stop moving The Dirt, you've embraced oblivion and are going to be pushed by the indifferent universe into a hole that is way harder to escape.
Personally, I've been looking at my stream and noticing how similar it looks to the streams of other people. And I've noticed that the streams of those other people, led them far too frequently to suicide, death by loneliness... So here I am, desperately trying to shovel an escape trench to a different end. Wish this greyface cabbage some luck, cause I'm gonna need it.
