Or maybe we just don't have a good understanding of how to learn it (and/or most people don't try). I can't visualise anything but the briefest of fuzzy flashes, and I'd love to learn, but I have no real idea how and not sure I'd invest enough time into it if I did because most of the time it doesn't affect me, so I'd "love to learn" the same way I'd "love to learn" better French (he says while 2 days overdue with his Anki deck) - it's an aspiration that often falls flat in the face of having to invest time.

How do you approach learning?

I'm very good at learning, can I maybe help? Talk to me.

You have wings. Don't talk yourself into not trying flying.

I started with a journal, 5 minutes or so of practice every 2 to 10 days.

First three I spent with my eyes closed, boxed breathing and not thinking of anything. It is hard to engage your mind in something while it's thinking this and that. That has to stop first.

Then I'd try to localize a point. Move it around. A spot of my attention.

Then try to understand what it would feel for it to be red, or green.

Then I'd add a second point, and spread them apart or move them in closer together.

Then I'd make one larger, a spot. The other smaller, and move one around the other.

All of those are exercises for different days, and are progressively unlocked by succeeding at the previous exercise, not once but thoroughly.

Then you could try tracing letters, imagining yourself following the motion.

Putting letters together, one after the other.

Reading that backwards.

You should expect just that to take about 6 months of practice. Then it gets easier faster.
