A Book of Five Rings discussion

I picked this book up sort of as a philosophy book, I had heard that it was used as a model for how to succeed.

I didn't really see the relevance for business (maybe in the ruthless corporate culture years). These days, we are more geared toward synergy and teamwork, and having a philosophy of a quick take down with no puffery doesn't really fit with modern business culture.

However, I did find that my strategies while playing online games improve dramatically. My play style used to be very safe and full of healing and self preservation. Now, I dominate my opponents. Particularly in Magic the Gathering Online, these matches are over very quickly with me losing very little hit points.

I wanted to start this thread, because I was curious to see what applications other readers found for this work. If used as a way to succeed, how is the philosophy applied?
