一生的时间有限，应该把它用到最想做的事情上去；哪怕是有一件最想做，还有一件次想做，把时间给最想做的。

One has only limited amount of time in his life, so he should put them onto the activities that he wishes mostly to take on. E.g, if there is a thing he wants mostly to achieve,  and an another which he also wants to but is at less eagerness, then take the first one.
