When we are too young, we do not judge well; so, also, when we are too old. If we do not think enough, or if we think too much on any matter, we get obstinate and infatuated about it. If one considers one's work immediately after having done it, one is entirely prepossessed in its favor; by delaying too long, one can no longer enter into the spirit of it. So with pictures seen from too far or too near; there is but one exact point which is the true place wherefrom to look at them: the rest are too near, too far, too high, or too low.
