I read this book several years ago and got a real buzz out of it. Excuse the pun! I was already embarked on a portfolio lifestyle, but only just setting sail at that stage. Now, several years later, I find I constantly refer to this metaphor, of the fleas and elephants, as I see so many people exiting the world of corporates and joining the swarms of fleas. If you are just moving into such a situation, I would recommend reading this book. I think you might find it quite heart warming and possibly informative
