Success doesn't hinge on some grand, operatic idea or the "will of the people."

成功不只取决于宏伟的理想主义 或以某人的意志为转移

And it can be lost with the slightest hesitation.

稍有迟疑 就会满盘皆输

But you've got to take a lot of these pictures,

但由于你拍摄了许多张X光片

Even though you could take a full three dimensional of your body,

所以即使CT能提供全身的三维影像

take off and peak around 19--late '20s.

大幅增长并在二十年代晚期达到顶峰

There you see the drop around the crash time even more dramatically.

可以看到在大萧条时期的大幅跌落

no matter how well you do,

不管你做得多好

it's a competitive business.

竞争十分残酷
