The finest edge is made with the blunt whetstone.

Sharpness comes from being worked against something that has none. The dull, patient, unglamorous material is exactly what puts an edge on a blade, and the same holds for people: the tedious task, the slow colleague, the objection that is not clever but will not go away. Being ground against resistance is how capability actually forms. Nothing polished makes you sharper.

Consider what the dull part of your work is quietly building in you. Give it your full attention once this week instead of hurrying through to reach the interesting part.
