Which Books should an Entrepreneur Read?

If I could go back in time to 2010 and give myself a single advice what to do, to be a more successful entrepreneur, what would it be?

My answer:
Max, read (in this order) these books:

1) The Lean Startup
The Lean Startup: How Today's Entrepreneurs Use Continuous Innovation to Create Radically Successful Businesses, Eric Ries

• This book explains that Lean Startup is a good idea (get feedback early, test your assumptions). 
• However, even if you are really convinced, it's hard to apply. You need...

2) Running Lean
Running Lean: Iterate from Plan A to a Plan That Works, Ash Maurya

• This is a "cook-book", especially for web startups. It makes the theory and stories from Lean Startup applicable. But this book does not explain the why. That's why you need to read Running Lean second, when you actually start.
• If you follow this book by the letter... you still fail horribly. Maybe even harder. It's because you also need to read ...

3) The Mom Test
The Mom Test: How to talk to customers & learn if your business is a good idea when everyone is lying to you, Rob Fitzpatrick

• This book explains how to talk to people and get real data instead of nice, but dangerously misleading compliments. 
• I think I summed up a lot of the content of the book in a slide deck on slideshare. Takes ca. 45 Minutes to consume.

That's it. What is you single best advice?
