Sometimes two things are to be done at the same time.
有时候,在同一时间有两件事要做。
We can only take up one of them;
我们只能选择其中一个;
the other has to wait or be given up.
另一件事只能等到以后再做或者干脆放弃。
But we know the future is uncertain—
可是你知道,未来不可预知,
the changed situation may not allow us to do what is left behind.
今后的变化可能不允许你完成剩下的这件事。
Thus we are caught in a fix and feel sad.
所以你会觉得郁闷、难过。
How come those nice opportunities and brilliant ideas come all at once.
为什么这么好的机遇和绝妙的想法会聚集到同一个时间?
It may happen that our life changes suddenly
你的一生可能会发生戏剧性的改变。
just because we choose one over the other.
有可能就是因为你选择了这件事而放弃了那件事。
