Words should be employed as the means, not as the end: language is the instrument, conviction is the work. - Joshua Reynolds

No Art can be grafted with success on another art. For though they all profess the same origin, and to proceed from the same stock, yet each has its own peculiar modes both of imitating nature, and of deviating from it, each for the accomplishment of its own particular purpose. These deviations, more especially, will not bear transplantation to another soil.

A painter must compensate the natural deficiencies of his art. He has but one sentence to utter, but one moment to exhibit. He cannot, like the poet or historian, expatiate.

You must have no dependence on your own genius. If you have great talents, industry will improve them; if you have but moderate abilities, industry will supply their deficiency.
