War is what I was referring to by "different kind of martial art" - consider the etymology of the word "martial", and remember it's not just the mysterious East that has a long tradition thereof :-)

Indeed the article doesn't explain how to get started in the first place - I know of no comprehensive theory of that, but would be very interested in one.

But it does discuss a range of scales beyond the personal and daily one. How often do people say "I'll take a year off college to tour Europe" or "I'll (start a company / raise a family / whatever it is the person really wants to do) - but I'll get an MBA first"? I think "fire and motion" throws decisions like that in a new light.
