What I like about this approach is that it goes back to looking at what your problems actually are.
A lot of self help and social media sells you virtues in the form of solutions looking for a problem. It makes people go around with hammers of virtue seeing everything as a viceful nail they can hammer down. And of course they see the nail in other people first.
That seems to fly over a lot of heads.
Anyone who actually meditated will tell you the process of fixing yourself through meditation is painstakingly slow, you mostly become aware of how your mind does not do what it is supposed to, and if you stop meditating you quickly lose all progress.
What the post describes is essentially some form of micro journaling to build a cached hashmap of the thought patterns you want your mind to have.
If you want to reinforce your current beliefs do the opposite. Write nothing down. Do what comes to your mind first. You do you.
If I had a garnish that turned anything objectively stupid into something that has objective value it would probably revolutionize chain-of-thought reasoning.
For example when you get very aroused your pupils dilate. Your brain fixes this for you so you don't feel like more light is hitting your retina even though it does.
When you are high on psychedelics you can experience this though as the world getting literally brighter and darker with your mood. Feels like you are shaping reality with your feelings? As soon as the drugs wear off the effect is gone but you still have the memory that it happened.
Weirdly enough, the same way dreams can feel more like an episodic story or more like an immediate experience, that unfiltered dreamlike experience feels more real than the rest of the trip. Maybe because it literally is closer to reality because it was less bring-filtered, or maybe because the contrast between this and the hallucinations of wallpaper shifting before your eyes put the search for "real reality" into your head in the first place, now the concept of more or less reality is in your brain as an experiential concept. Now you have the memory of having struggled for real perception and achieving it.
Like in inception: you fell into a dream, you are trapped for longer than you anticipated and don't like it and want to wake up. Weeks later when you have a deja vu it triggers the uncomfortable feeling that your mind is playing tricks on you. Are you dreaming now?
Though this is not schizophrenic. From what I was told from someone who had schizophrenic episodes it makes you completely unable to tell apart illusions from reality.
I think you hit the nail on the head why we are in a doers world. Musk is a good representation for doers not because of what he does and achieves, but because of the way he whips his employees into shape.
He is very vocally against giving resources to thinkers and letting them slow cook.
