An optimist is a girl who mistakes a bulge for a curve.
乐观的人，等于是把（自己身体上）凸出来的部分也错认作曲线的女孩子。
An incurable optimist; an incurable smoker.
坚定不移的乐观主义者；不可救药的烟民
The man who is a pessimist before forty-eight knows too much; the man who is an optimist after forty-eight knows too little.
未逾四十八岁的悲观主义者，是知道得太多之人；而年逾四十八岁的乐观主义者，是知道得太少之人。
