While you may think that a life without constraints is one you want to live, it's more likely to paralyse you. Throughout this book David Epstein shows readers that a lack of constraints reduces creativity, increases distraction, and reduces happiness and longevity.

One example I liked was citing a 1950s book called By Space Ship to the Moon. It was geared for teens and laid out the current technology, followed by the steps needed to get to a moon landing. It showed a sharp contrast to A City on Mars which looks at our current quest for Mars. Unconstrained billionaires are throwing rockets into space without doing the concrete science on how to feed people in closed loop systems.

If you're looking to have a happier more creative life, read this book and then embrace constraints.
