Show it, don't announce it

Watch two people start the same job. One spends the first week telling everyone what they did at their last place, how it should be done, where this crew is getting it wrong. The other keeps quiet, watches the line, asks the dishwasher why he stacks the trays that way. Six months on, it's the second one the shift lead trusts with the hard nights.

Epictetus, who taught for decades and had no patience for talkers, drew the line clean: "Never call yourself a philosopher, nor talk a great deal among the unlearned about theorems, but act conformably to them" (Enchiridion 46, Carter). Don't advertise the wisdom. Do the thing the wisdom tells you to do, and let people notice or not.

This is where Staying Teachable begins, and it's the move for the whole week: the student shows by doing, not by declaring. The moment you're busy proving you already know, you've stopped being able to take anything in. A closed hand can't be handed a tool.

The teachable worker isn't the one with nothing to say. It's the one who's decided that today, mostly, watching beats talking.
