可持续发展不再是选择;它是当今世界生存的必要条件。
We must be free not because we claim freedom, but because we practice it.
Strength does not come from physical capacity. It comes from an indomitable will.
Intelligence is the ability to achieve goals in the world.
The only way to deal with an unfree world is to become so absolutely free that your very existence is an act of rebellion.
真正的力量来自于内心的平静。
