What Bruce Lee really captures here is permission—not just to borrow, but to discard reverence itself. Most of us stay loyal to methods simply because they're traditional or because we've invested time learning them, but Lee is saying that sentimentality about *how* we do things is a luxury we can't afford if we want results. A surgeon might discover that a musician's approach to hand steadiness improves her technique, or a manager might find that a competitor's scheduling system works better than her industry's standard practice—and Lee would say, take it without apology. The truly pragmatic person isn't the one with the most coherent system; it's the one brave enough to raid from everywhere and leave behind what doesn't serve.
