Query: Learn something new each time

I've only read this book twice, and I'm just about to graduate from college so I'm no Lean expert, but I seem to get something new, or more understand something at a little deeper level when I read this book. Great introduction to Lean. One of the things I like about the book is how it tries to change your mindset to think more Lean. The characters set up something in the factory they think aligns with Lean objectives (and you would generally think it's a good idea if you have no formal training in Lean and haven't "learned to see"), only to have the "sensei" come and tell why that isn't the best approach. Then it tells you what would be a better option. I think this is a must-read for anyone interested in Lean.
