If it was good enough, you could just keep at it, it would still work. If that’s the case, there’d be no reason to change. Especially, there’d be no reason to undergo the ego-shredding life-collapsing change of dissolving your old mind and growing a new one.

No one changes unless they have to .

Cut a chrysalis open and you will find a rotting caterpillar. What you will never find is that mythical creature, half caterpillar, half butterfly... No, the process of transformation consists almost entirely of decay.
