Reading Los Tónicos De La Voluntad by Santiago Ramón y Cajal
I've been meaning to read this book for a long time. I don't think I've ever read anything from him, so it'll be a good start to see if I want to dig deeper.
This book talks about rules and tips on how to do investigation. Which I'm sure I can apply to learning and reasoning in general. I always evaluate my conclusions and put my knowledge to the test objectively, but I'm sure there are many things I don't do properly. So I'm looking forward to improve my approach.
