I just finished reading a book called
The 4 Hour Work Week by Tim Ferriss. He was on one of the blogger panels at South by Southwest, and just blew up in popularity after it. This book applies directly to with what all of us are doing, and is an absolute must read.
On the surface this book is about outsourcing your life, cutting out things that are non productive and taking mini retirements all year..... but the overall message is more about going out and living the living the life you actually want right now. What use is there to have $10 million in the bank when you're 70? Why not have fun with that money now?
One of the main ideas I took away from this book was the 80/20 rule. Most of our companies would be much more profitable, if we focused on the 20% of things we do that actually produce results. Tim also has a great theory about a lot of people who do "work for works sake". You're basically just being busy, but not being productive. I know I do this all the time, and it's a lot easier for me to actually see that now.
Seriously, go buy this book now. Grab a highlighter and mark it up. Then re read it again. I've read it 3 times in the past week and I pick up a few more ideas each time. This might end up being the next Freakonomics or Tipping Point.
