"Accentuate the positives and reduce the negatives in your life." Reduce stress. Put things in perspective. Hire someone to mow the grass if you don't like doing it. Don't fight battles that cost you the war.
Some points of this book seemed a little bit excessive if taken literally, but I think the book as a whole is more of a self-help book for examining how you are spending your time. Sometimes the "accentuate the positives" and "reduct the negatives" is over-simplistic, but the stark examples help drive home a point as well. Since I enjoy having perspective shaken up once in a while, I enjoyed this book. If you're not both open-minded and willing to take advice with a grain of salt, this book may not be a good fit for you.
