In this short book, Gary Belsky and Tom Gilovich catalog a menagerie of mental mistakes that cause people to spend more than they should. What might have been a boring topic becomes fascinating thanks to an engaging style and plenty of anecdotes and examples. This book covers more than a dozen psychological barriers to wealth and explains how to prevent them from sabotaging you. [My review.]
