The Willpower Instinct: How Self-Control Works, Why It Matters, and What You Can Do to Get More of It by Kelly McGonigal

1.0

Don't waste your time. This book is overly reliant on anecdotes and poor examples. For a better, more concise and more scientific approach to the same topic, look at Kahneman's Thinking Fast and Slow, along with lots of other interesting and useful facts about the brain.
