实现明天的唯一限制是我们今天的疑虑。
The only limit to our realization of tomorrow is our doubts of today.
A story is not finished until it has taken the worst possible turn.
The difference between ordinary and extraordinary is that little extra.
The only thing you can do is give all you have on that particular day.
【译文】他人骑大马我骑毛驴,仔细想想,我不如他,回头看了一下,还有不如我徒步肩挑的人呢。
