I haven’t gotten so far in the book. But at the beginning of the book, Dave mentioned Dual n-back exercise as a “permanent RAM upgrade for your brain”.
It seemed like a no-brainer to try it, so I searched google play for it and installed the first hit I found.
I like the sound of that! 🙂
The first test was somewhat easy but started to struggle on the second batch, where I had to remember two steps back.
hard to explain, so you should try it instead 🙂
