Now then, you of noble mind, who love this profession, come at once to art and accept these precepts: enthusiasm , reverence, obedience, and perseverance. As soon as you can, place yourself under the guidance of a master, and remain with him as long as possible.

If you set out to copy after one master today and after one tomorrow, you will not acquire the style of either one or the other, and you will inevitably become fantastic, because each style will fatigue your mind.
