The only limits in life are the ones you set for yourself.
生活中的唯一限制是你为自己设定的限制。
The only way to deal with an unfree world is to become so absolutely free that your very existence is an act of rebellion.
The journey of discovery is as important as the destination itself.
——〈在广州岭南学堂的演说〉，1912年5月7日
有时候最真实的东西反而是你看不见的。
The highest manifestation of life consists in this: that a being governs its own actions.A thing which is always subject to the direction of another is somewhat of a dead thing.
The best way to predict your future is to create it.
