We don’t say a guitarist will stagnate if he doesn’t learn the drums, we don’t say an architect’s will stagnate unless she learns the ins and outs of Greek architecture, simply knowing how to do more things doesn’t improve your creativity, it may even impede it.
A working artist tends to be good at making one thing really good, they’re like actors in that all of them have a limited range unless they’re some sort of prodigy amongst men.
