But you've only got one life. So which is your "way of life": aikido or skiing?
I would describe them both as being aspects of my way of life. One doesn't necessarily preclude the other...or maybe more to the point, it depends on the situation as to which might. I would argue everyone has a unique expression of any given way, which implies to me that all ways of life are subservient to individual way of life.
So in other words, i don't think one has to devote one's life to aikido to include aikido as "a" way of life...never mind periods of time where one might simply want to make it the only "way" they try to emulate.
