"The cost of oblivious daydreaming was always this moment of return, the realignment with what had been before and now seemed a little worse."
白日梦的代价总是这一刻的回归，与之前的一切重新对齐，而现在看起来似乎更糟了一些。
如果你在小事上无原则，那么大事上一样没有原则。
Dreams need courage, and even more action.
译文：人必须在事情上磨炼，才能立得住;才能做到安静时也安定，行动时也安定。
Perhaps one day you muster the courage, to make a clean breast of everything in the heart only ended up to let others see the joke, because they did not understand you to say what, also don't know why do you think things are so important, say, almost cried out. I think the worst thing in the world, than with full of heart and secret, but no one can tell, but no one can understand!
Mathematics is not just about numbers, equations, computations, or algorithms: it is about understanding.
