Looking back also clarifies that “principles” are not rigid rules. They are tested hypotheses about how reality works. When reality disagrees, the principle must evolve—or you accept the cost of clinging.
The higher-level view is that life is choices under uncertainty. Build a machine that handles uncertainty better—through feedback, reflection, and redesign—and you improve both results and steadiness in the middle of chaos.
