I criticized a carpenter working for me recently for using dull tools. He excused himself by saying that he had been too busy to sharpen them. He had been working for weeks with a dull saw, and with a plane which had notches in it, leaving ugly ridges on the boards he was planing.
He had probably wasted more time in working with dull tools than would have been required to sharpen them several times, to say nothing of the inferior work he was turning out.
There are multitudes of people who never do good work because they never prepare for it, never put themselves in a position to do good work—they never sharpened their tools; never trained themselves for it, and they go through life botching their jobs…
