And you realise you're doing a public service in making people happy - as a musician you can give people something a doctor, a lawyer, a politician cannot give them that. It's not scientific. It's spiritual - a good feeling. And although you don't know them personally, the audience are like your friends.
你意识到你在做一件让人们快乐的公共服务——作为一名音乐家，你可以给人们一些医生、律师、政治家不能给他们的东西。这不是科学。这是精神上的——一种美好的感觉。虽然你不认识他们，但是观众就像你的朋友一样。
