对这个世界有所助益是获得快乐的唯一途径。
你不能对任何情况生气,你得嘲笑它。
He who is content is always happy; endless desires never find satisfaction.
I was not born blind, I became blind at the age of 12. So I have seen the world and I know what things look like. When I sing about love and pain, joy and sadness, I know what I'm singing about.
