I love this quote from Richard Koch in the third edition of The 80/20 Principle.
Happiness is a duty. We should choose to be happy. We should work at happiness. And in doing so, we should help those closest to us, and even those who just stumble across us, to share our happiness.
Richard Koch
Initially I was sceptical to pick up the book since I felt like I already had a good understanding of the principle. But I’m glad I did because I discovered above.
If you pick up a copy remember to apply the 80/20 principle while reading. The book is laid out in a way that you can read a heading, decide if it’s relevant or not, and if it’s not then you can skip it. In fact Koch mentions multiple times throughout the book that if this section/chapter isn’t relevant for you than you should move on!
