No pain, no gain
Sibyl: You look exhausted after that run.
Debra: Yes, I'm pretty tired. It was five kilometers.
Sibyl: That's a long way. How often do you do it?
Debra: Twice a week.
Sibyl: Goodness! Don't you think that's too much?
Debra: No, not at all. It keeps me healthy and helps me to lose weight.
Sibyl: It would be good if I could lose some weight but I couldn't do what you do. My body couldn't stand it.
Debra: No pain, no gain.
No pain, no gain这成语，原是健身运动班的口号，现在仍常用于运动界，但也可引伸用于其他场合，意思是「没有辛苦，就不会有收获」。这成语的另一说法是no gain without pain，例如﹕He has had a hard life, but now he is rich enough to lead an easy life. There is no gain without pain（他一生吃过不少苦，但现在有点钱，可以轻松过活。不辛劳，就不会有收获）。
一九八九年，英国首相马卓安推行新经济政策，说If it isn't hurting, it isn't working（政策不带来痛苦，就不会有成效）。这是no pain, no gain的另一说法。
英文还有两句成语，和no pain, no gain意思差不多。一是no cross, no crown，直译是「没有十字架，就没有王冠」，用耶稣死于十字架上而获得天国光荣作比喻。另一成语是through hardship to the stars，直译是「经历困苦，而踏上明星之路」，以「明星」比喻名气和成就。例如﹕(1) We cannot have democracy unless we fight for it. No cross, no crown（我们不为民主奋斗，就不会有民主。没有牺牲，不会有收获）。(2) Starting as a clerk, she made her way through hardship to the stars and became chief executive of a multinational corporation（她最初是个文员，经过艰苦努力，成就卓著，成为一跨国公司的行政总裁）。
