Best books/videos on how to be an autodidact?

Ultimately, IME, no resource will ever tell you how to practically become one but personally I found these resources helpful:

* 'Mastery' by Robert Greene

* Learning How to Learn (on Coursera)

* I find OCW (on YouTube) pretty inspiring

* 'Ultralearning' by Scott H. Young

* Ask lots of questions, keeping asking and then ask some more. You have Google and YouTube so don't worry, you will find an answer... eventually.

+ I'm naturally a very curious guy and my mind won't just rest until I learn (more about) that thing, whatever it might be.
