无论你的背景如何或来自哪里，只要你有梦想和目标，这才是最重要的。
It doesn't matter what your background is or where you come from, if you have dreams and goals, that's all that matters.
你无法回到过去改变开始，但你可以从现在开始改变结局。
The joy of solving a mathematical problem is unparalleled; it is a moment of pure intellectual triumph.
Life is short, make every moment count.
让生活从此变成一首欢乐的诗。
