Hi!
A few years ago I came across a book that sounded really interesting about mastering skills and learning things quickly.
It was written but a guy (maybe a psychologist, not sure) that invented a method to master skills, he tested this method on his daughters in the 1920s (maybe) and they became super smart. I believe the book was called "the method of…" Or "… method".
I know this is a bit of a vague description but I can't find this book anywhere and don't know how it's called. Maybe someone has read it and will be able to guide me to it.
Thanks in advance for all the input!
