I found the article to be entirely useless, since it doesn't cover concrete techniques from any traditions, whether that's St. Teresa of Avila's Interior Castle or Buddhist works. The best "focus techniques" are usually found in "occult" books - I quote because there is no real system and it's all disjointed and makes no sense. Anyway, here are some decent focus exercises: 1. Take a book. Count the words on a random page. Remember the word count. Count them again, confirm the word count. This is HARD - you stay focused for several minutes, avoid the temptation to actually read the content, and have to hold the current number + the last total in your mind, which stresses your WM. 2. Just count to 500+ while laying down and not moving (usually before bed). I find counting heart beats and breath affects the natural rhythm and messes with it, though Buddhism loves that. 3. Spill a bunch of marbles / legos on the floor and pick them up ONE piece at a time. 4. Dual n-back from the Brain Workshop (free, I am not associated) app. See more info here: https://gwern.net/dnb-faq https://gwern.net/dnb-faq Overall, all of these were never really proven to do anything and the question whether "perfect focus" impedes creativity is open. Furthermore, one of the true tests of "perfect focus" is when you forget yourself in the moment and lose track of time - that only seems to happen when the situation is extremely stressful / interesting, and none of the techniques reproduce it. It's also unclear if any of the exercises carry over to work. They teach you what focus feels like though - you definitely can't be on your phone and doing the word count exercise. Funnily enough, video games or movies also teach you what focus should be - you are staring at the same thing for hours without needing to get up, get tea, or otherwise distract yourself. Anyway, that was a bit of a rant, but as an "expert" in the subject matter, I am pretty hard-pressed to find anything concretely useful there. It definitely doesn't fall into the "universally good" category like "Get enough sleep, lift, do cardio, don't eat sugar, brush your teeth, don't get sun burnt every day", etc. club.
