Yes, in the interview with Mike Wallace it came up. If its in your self interest, you can make sacrifices. But its intertwined with "whom to love" and why the notion to "love your enemy/neighbor" is ridiculous as it would be indiscriminately, because the currency of love is virtue. See the Mike Wallace interview, its awesome -and eye opening.
I'll check it out. I do think that adhering too strictly, as in entirely unwaveringly even in the slightest, to any belief/philosophy/system is limiting and ultimately a restraint. I learned this a lot from Bruce Lee, who was arguably just as good of a philosopher as a martial artist.
"Man, the living creature, the creating individual, is always more important than any established style or system."
"All fixed set patterns are incapable of adaptability or pliability. The truth is outside of all fixed patterns."
"...truth exists outside all molds."
perhaps more controversially:
"Styles tend to not only separate men — because they have their own doctrines and then the doctrine became the gospel truth that you cannot change. But if you do not have a style, if you just say: Well, here I am as a human being, how can I express myself totally and completely? Now, that way you won't create a style, because style is a crystallization. That way, it's a process of continuing growth.
Because of styles, people are separated. They are not united together because styles became laws. But the original founder of the style started out hypotheses, and now it has become the grospel truth. People that go into them became their product. It doesn't matter how you are, who you are, how you are structured, how you are built, how you are made. It doesn't matter. You just go in there and be that product. And that, to me is not life.
Take no thought of who is right or wrong or who is better than. Be not for or against."
TL;DR: I'll watch the video now, but I don't adhere unwaveringly to any style/philosophy/system, even Ayn Rand's. Some people would argue that it makes me simply a lukewarm/half-hearted Christian, Stoic, objectivist, etc, but I would respond by saying that I don't define myself entirely as a Christian or a Stoic or an objectivist.
It's easier to say what you aren't than what you are. One way I seek the truth is to eliminate what is not true. I may never get to the whole truth, but I'll move closer and eliminate wrong beliefs and wrong actions. Like Bruce Lee said,
"In building a statue, a sculptor doesn't keep adding clay to his subject. Actually, he keeps chiselling away at the inessentials until the truth of its creation is revealed without obstructions. Thus, contrary to other styles, being wise in Jeet Kune-Do doesn't mean adding more; it means to minimize, in other words to hack away the unessential.
It is not daily increase but daily decrease; hack away the unessential."
