Why do I miss things on my rounds even though I show up and check?

You walk the rounds. You check the boxes. And still, something gets past you — a sign you should have caught, a change you should have seen before it grew. This is not laziness. You are showing up every time. The problem is smaller and more exact than your character. Doing the rounds and knowing the rounds are two different skills. You have built the first. You have not yet built the second — the eye that knows what each check is really testing for, and why it matters when the answer is wrong. Nobody handed you that eye. You build it, one missed thing at a time. This is within your power to fix. Not by trying harder at the same motion — that only tires you. Fix it by studying your misses the way a craftsman studies a bad joint: closely, without excuse, until you know exactly what you were never taught to see.
