Each piece of information you consume and digest offers immediate benefits - you gain the knowledge you sought and it stays with you, forever. That knowledge then mingles with all the other ideas you've collected and thought up. Reading and studying throughout your life offers a compound effect - providing you with mental models to help you think better. With that said, here is the list of book and articles I've read which have broadened my mind in some way.
