Sustainable development is not a choice, but a responsibility.

The greatest thing in the world is to know how to belong to oneself.

Youth is not a time of life; it is a state of mind; it is not a matter of rosy cheeks, red lips and supple knees; it is a matter of the will, a quality of the imagination, a vigor of the emotions; it is the freshness of the deep springs of life.

I have to remind myself that some birds aren't meant to be caged. Their feathers are just too bright. And when they fly away, the part of you that knows it was a sin to lock them up DOES rejoice. Still, the place you live in is that much more drab and empty that they're gone. I guess I just miss my friend.

Never stop learning, because the world never stops changing.

努力工作，保持善良，永不放弃。成功自会随之而来。

预测未来的最好方法就是创造未来。
