The 60 Minute Startup: A Proven System to Start Your Business in 1 Hour a Day and Get Your First Paying Customers in 30 Days (or Less) by Ramesh Dontha
Have you ever had a book jump off the desk, put on it's running shoes, grab you by the arm and drag you along into its world? This one does that and at a frenetic pace too.
I worked with the agile methodology when I was still in that corporate world, and there were some things I didn't understand until I read this book. It is amazing.
I also love the way he started each chapter with an actual case study a name and what this person did or didn't do that illustrates the point of the following chapter. I couldn't wait to turn the page to see what the story was going to be this time.
If this does not change the way you view your life and your work, then I'm not sure where that leaves you. This is an exciting book.
