You don’t have to outshout them. Outgrowing them is quieter and way more permanent.

Arguing with people who do not rate you keeps you inside their frame and spends your effort on their opinion. Growth is the alternative, and it works without their participation, because eventually the distance is simply there and nobody had to be persuaded of anything. It also lasts, which a won argument does not.

When you want to prove somebody wrong, put that same energy into the thing itself. Set a date a year out and see where you stand. The quiet version of winning is slower and it does not come undone.
