I personally observed that write down things with pen and paper help memory, I also observed that reading thing on paper instead screen help again and finally mere write down in digital help comprehension like on paper but being able to modify anything "cost-free" reduce a bit the attention you punt in writing. Vocal dictation is awful.

But there is a big but: I'm really disorganized. I try to be organized on regularly basis and it work at first, after start to decline until I reach a point that I came back and focus again on reorganize.

In this scenario my digital world is essentially organized thanks to automation and periodic cleanup, my physical world of sparse note on any peace of paper I may get at hand, left anywhere, forgotten, only the ticket I regularly collect when I refuel my car and I periodically forget to register with only casual look at my on-line bank account... Well make me practically unable of such proper&clean records...

Long story short: a prize, but personally I have to stick with org mode...
