Talent is long patience.
Everything you want to express must be considered so long, and so attentively, as to enable you to find some aspect of it which no one has yet seen and expressed. There is an unexplored side to everything, because we are wont never to use our eyes but with the memory of what others before us have thought of the things we see.

Context

“then, the next Sunday while we breakfasted together, he would give me his criticisms, driving into me by degrees two or three principles which sum up the drift of his long and patient exhortations: "If you have any originality," said he, "you must above all things bring it out; if you have not you must acquire it." Talent is long patience. Everything you want to express must be considered so long, and so attentively, as to enable you to find some aspect of it which no one has yet seen and expressed. There is an unexplored side to everything, because we are wont never to use our eyes but with the memory of what others before us have thought of the things we see. The smallest thing has something unknown in it; we must find it. To describe a blazing fire, a tree in a plain, we must stand face to face with that fire or that tree, till to us they are wholly unlike any other fire or tree.” source
