"He is a poor disciple who does not excell his master." Leonardo da Vinci
I think this is very true, and I think that for the most part people are afraid to do so. I think it's also a very good goal to strive for.
P.S. da Vinci wasn't just talk, he really did surpass his master, Andrea del Verocchio, Verocchio was a painter and sculptor but after da Vinci began to surpass him in painting Verocchio stopped painting and stuck to sculpture.
