Failure is not the mother of success. It doesn't automatically lead to success on its own. What truly drives personal growth is continuous attempts and the feedback that results from them. It's the positive feedback that comes from success that reinforces behavior, not failure itself. Therefore, if something continuously causes you pain, frustration, and lacks effective feedback, stopping it is not giving up—it's a rational form of self-renewal. Blind persistence is often only due to sunk cost fallacy, not because the path is truly correct. Human energy and cognition are limited systems. Continuous input without output and cleanup only creates burden, much like how a computer slows down when its memory is filled with useless data. Growth is not endless accumulation; it's a cycle of input, processing, output, and elimination. Only when you begin to express, practice, and output do you truly know which things have become part of you.
