Upbeat is for people who want to feel good about their cause: the reformers, the progressives, the revolutionaries, the utopians, the collectivists, and the rest of the altruistic scum of the earth. Why do these people want to feel good? They want to feel good in order to convince themselves that they are good.
乐观的人是那些想要对自己的事业感到满意的人：改革者，进步主义者，革命者，空想主义者，集体主义者以及地球上其他无私的败类. 这些人为什么要感觉良好？ 他们想要感觉良好，以便说服自己自己是好人.
