Constraints always force you to make choices. Everyone has a finite amount of time, money, energy, mental bandwidth, and so on.

Work is important, but you can also be successful at building a family, having great friends, serving in the community, becoming physically fit, and so on.

People are trying to cram more and more activities into every day in pursuit of productivity. Don't fall for it. You need to be getting enough sleep to feel good. Sleep is not a necessary evil — it's something you need to do to charge up your batteries over the long haul.

Work - life balance is not a myth. It can be achieved, but be aware it's dynamic rather than static.

The underlying message from this book is by taking quality time off, you'll achieve more in less hours with your work.
