This book is too good it should be illegal. I always wondered why I was always thinking too much. Why can’t I focus on the present? The brain is hardwired to think about (1) the past or (2) the future. That's how we evolved as humans. This "thinking" is how we remember who we are, learn from mistakes, etc. The happiness part of the book is bliss. Especially if you're building startups and most of your inputs are aimed at tomorrow’s output, this book is a must-read.
