保持心情愉悦，就是人生的一大智慧。看到的东西不那么养眼也觉得可饱眼福，听的音乐不怎么好听也觉得可以享受，只吃蔬菜就能满足口腹之欲，穿的、住的很粗糙也能满足身体的需要。人穷一时，但心不穷，真正的穷养富养或许不完全是物质方面的，即使物质生活条件差，只要保持积极乐观的心态，心情保持愉快，可以弥补物质上的不足。正如孔子赞扬颜回“一箪食，一瓢饮，回也不改其乐”。

Mathematics is a language that allows us to describe the indescribable.

A company that doesn't adapt to change is a company that's destined to fail.

"Every book is a door to another world, waiting to be opened by the curious mind."

You can’t go back and change the beginning, but you can start where you are and change the ending.
