This is a rare book. I can hardly find any book that discuss about personal failure in Japan.
It taught me a lot about failure. Route he took was an unusual route. The way he made investment are different from others company. And what he did, I might do the same. But now, this book give me a chance to rethink, what I would do in the future.
Business, investment , profit, liability, cash flow, human resource, marketing technique, are the keys topic that mention and worth a great deal of time to think deeply about it.
Specially in the case of Y-cube.
Next book I would like to read is, how the mighty falls.
