There is no beauty unaided, no excellence that does not sink to the barbarous, unless saved by art.
Attain and maintain a reputation, for it is the usufruct of fame. A stiff climb, for it is the issue of excellence, as rare as mediocrity is common.
There is none who cannot teach somebody something, and there is none so excellent but he is excelled.
Excellence resides in quality, not in quantity. The best is always few and rare; much lowers value.
