This is a fantastic, highly-actionable book that you won't regret reading. Insofar as it's a guide to the good life, it boils down to a few high-level principles:

* Be happy with what you've got
* Don't worry about things you can't change
* Strive to become stronger by intentionally putting yourself into uncomfortable situations

They're great high-level goals, and the remainder of the book is tactics for achieving them (and some boring history stuff.)

This book is so good that I'll buy you a copy---even if I don't know you :) Just ask!
