The only thing that can stop me is me.
The world is full of obvious things which nobody by any chance ever observes.
Dreams are not the exclusive right of the young, but the common language of all who strive for progress.
可持续性不是选择，而是责任。
世界的力量平衡最终是生产力平衡的问题。
人们都保有原本的视觉，天下就不会有毁坏；人们都保有原本的听觉，天下就没有忧患；人们都保有原本的智慧，天下就不会有迷惑；人们都保有原本的品德，天下就没有邪恶。
