How much did I like reading this book? 6/10

I was pretty excited to read this book. Becoming a "superlearner" with knowing the best techniques is quite appealing.
However, I must say I ended up disappointed.
First half of the book, I didn't learn anything, it's mostly self-talk about introducing the topic. I even suspect the author wrote this non essential part to make his book "longer". Maybe he was worried his book was only 50 pages long?
The second part was not moch better. It confirmed the author is falling short on his promise.
I surely already knew about some memory tricks, like the palace, and I didn't learn anything new here. Quite the contrary, I read better explanations in other books.
Other techniques he discuss (briefly) are: pre-reading (skimming), asking questions (to fight passive reading), spaced reptition, speed-reading (subvocalisation, moving the eyes in fewer "chunks"), Feyman learning technique.

Overall, that was very basic.
I am readying Barbara Oakley at the same time, and find it much more interesting.

If you are afraid to miss any secret on learning, you can safely skip this book.

in our information economy, if you can’t learn quickly and effectively, you’re going to get left behind.
In the next decade, this trend is only going to accelerate as we transition into a society of nearly 100 percent knowledge workers.

CHAPTER 1: INFORMATION OVERLOAD AND THE EXPLOSION OF KNOWLEDGE

Every year, there are six hundred thousand to a million new books published in English alone.
And that’s just books. More and more, as a society, we are consuming our information from an ever-growing flood of newer media. blog posts, podcasts, audiobooks, and videos.
