Better to be intensive than extensive.
Perfection isn’t quantity, but quality. Very good things have always been small and rare; muchness brings discredit. Even among men, the giants are usually the dwarfs. Some praise books for their girth, as though they were written to exercise our arms, not our wits. Extension alone can never be more than mediocre, and the universal men who want to be in on everything are often in on nothing. Intensity leads to eminence and even — in matters of great importance — fame.
