伟大的领导者倾听多于发言。
A great leader listens more than they speak.
Do not put forward anything that you cannot prove by experimentation.
当每件事都是容易的时候，一个人很快的就会变的愚蠢。
To live is to choose, and every choice has its consequences.
The secret of change is to focus all of your energy, not on fighting the old, but on building the new.
