Mathematics is not a spectator sport—you have to engage with it to appreciate its beauty.
Stay the course. No matter what happens, stick to your program.
在每个大型程序内部，都有一个试图挣脱出来的小程序。
生命短暂，珍惜每一刻。
Order is the shape upon which beauty depends.
There is only one road in the world that no one but you can take. Where does it lead? Don't ask, just walk.
