Between the optimist and the pessimist, the difference is droll. The optimist sees the doughnut; the pessimist the hole!

Between the optimist and the pessimist, the difference is droll. The optimist sees the doughnut; the pessimist the hole!

乐观主义者和悲观主义者之间的区别是可笑的。乐观者看到甜甜圈;悲观主义者的洞!

-- Oscar Wilde 奥斯卡·王尔德
