Think and Grow Rich - Napoleon Hill

This book, despite the title, is not a step-by-step guide to becoming 'rich'. This is not one of those childish books that they sell to kids that tell you how to get rich at all...

Hill talks everyone who's anyone on the planet, from Thomas Edison to Bill gates and reveals their stories. This book is like Outliers, but focuses on their stories of success, and Hill brilliantly analyses these stories to come up with a set of common factors that all of these people have in their amazing success stories

And ESSENTIAL read.
