Loved this book. End of story. OK, I will expand on that for you...
This is actually a business book but when I read it it came to me how many different areas of my life it applied to. And before you get your knickers in a knot, it's like the anti-business book.
It was written by Jason Fried and David Hansson, the ideas presented only take up a page or two at a time so it's really easy to pick up and put down as you have time.
Here's a list of some of the "chapters":
Make a Dent in the Universe
Live it or Leave it
Meetings are Toxic
Press Releases are Spam
How to say you're Sorry
Send people Home at 5
... and the list goes on. I picked it up because I own my business, I love reading about economics, and it came highly recommended. I wasn't disappointed. Check for it at your library, I found it at mine!
