A cook who tastes before serving lets evidence interrupt confidence.

Confidence and correctness come apart more often than we admit, and the only thing that catches the gap is a check made after you already feel finished. Tasting is not doubt about your ability. It is a decision to let the actual result have the last word over your expectation of it. The habit is cheap, and it is usually what separates good work from work that was assumed to be good.

Find the place in what you do where you routinely skip the final look. The message sent unread, the figure carried forward from memory, the recipe you know by heart. Add the check back this week.
