I have no clue how I found Zat Rana's article, maybe back when he published at Medium, but that doesn't really matter, the good thing is that I did.
I really like the idea of consciously writing the things one keeps learning in life -in a kind of statement's list of what you need to pay attention to or you need to remind yourself- and review it often.
The writing (or the compilation) of the main ideas is a necessary part, but the revision is crucial. Sitting down once in a while and seeing what has changed, what maintains, what obvious statement isn't obvious at all anymore, and which new ones you can add to that are apparently missing.
To be honest, I wish I had written Zat Rana's list because there isn't a single one I wouldn't include in mine and because there is a lot of truth in each of them....
I have my favourites though: 1, 7, 14, 34, 40,
