Respect others' beliefs and views.

I’m positive that in 100 years much of what I take to be true today will be proved to be wrong， maybe even embarrassingly wrong， and I try really hard to identify what it is that I am wrong about today.

The past is a shadow that follows us, but it is our choice whether to let it define us.

"Cada livro é uma porta para um novo mundo, uma nova experiência."

没有“悲哀”提供平衡，“愉快”一词就会失去意义。
