I'm the reason your dog can't bark.

The only way to achieve true freedom is through self-discipline.

你不可能教一个人任何知识， 因为你只能帮助他自己去找他想学的。

Your so-called boss may own the clock that taunts you from the wall, but, my friends, the hour is yours.

I always believe that as long as you persist, nothing is impossible.
