The Most Important Thing Illuminated, by Howard Marks, covers a few principles for what he calls the superior investor – as if you are not going to be superior, you might as well just invest in index funds and not waste any time.
When I heard about the book, it was the regular version, but I believed the extra blocks of explanations – by famous investors as well as the author of the book – would be worth the extra time, and they were (I really which the font on the comments wasn't so small, though).
Most of the insights seem a little silly in summary form, but the details on how to handle them felt very useful to me – and I am very far from being a pro in the area.
Overall, strongly recommended.
