I have little doubt that emotion is paramount when writing and performing, it is without question the fuel that fires the imagination and electrifies the will power to dig into learning about yourself, creating and reproducing show after show.
Without emotion art is at best muddied and lacks edge, and I might add a big yawn to an audience. Who wants that huh?
What's the point if there is zero emotion behind your work? Ans: There is no point, you're just being a mimc, you're painting by numbers, imimitating, copying and wasting everybody's time including your own.
