Hard to choose just 5 but here goes:
- Emyth revisited by Michael Gerber. Essential read for every business owner.
- 80 / 20 Principle by Richard Koch. Best book about a well known, but vital principle.
- Why making money is killing your business by Chuck Blakeman. Not a well known book but a superb read on building a business for the long term.
- The 4 hour work week by Tim Ferriss. There are those that have read it and see a new perspective and world, and everyone else.
- The One Thing by Gary Keller. So important in today's mad dash world.
