Just one question, Mike-sensei (or Mike-shisho). I'm all for agreeing with that statement. I don't want to sound sexist and say that it's the "manly" thing to do, but a lot of the Hokuto no Ken philosophy coincides with that way of thinking.
But, what happens if your desire to control YOUR destiny conflicts with the plans I have for MY destiny? Does your paradigm approve the use of various means to resolve the situation, including, but not exclusive to, force, coercion, cheating, bribing, competition, negotiation, or intentionally creating a stalemate? The King of Fists, otherwise known as Roah, believes that anyone who gets in the way of his destiny is giving him an open invitation to let them experience the pleasures of pressure point obliteration. (Not that I endorse that kind of thing)
What I'm getting at is that, aren't there things that are totally out of your control or would require dedicating over 90% of your entire life to resolving it?
I guess the answer is for people to just suck it up and move on in that situation according to this philosophy, but I can understand why some people do not or can not accept that. Sometimes, trying to control your own life means you need to rattle the cages of other people, which, of course, is unpopular with the masses.
