Do not worry about your difficulties in Mathematics. I can assure you mine are still greater.
不要担心你在数学上遇到的困难；我敢保证我遇到的困难比你还大得多。
天天向前走，即便千万里路，也不嫌远；常常动手做，纵有千万件事，也不畏难。
我们都是由故事构成的，而这些故事从来不只是属于我们自己。
The time at our disposal each day is elastic; the passions we feel dilate it, those we inspire contract it; and habit fills up what remains.
成功来自于专注于真正重要的事情，并放下其余的一切。
It’s not what we do once in a while that shapes our lives, but what we do consistently.
