The world is full of obvious things which nobody by any chance ever observes.

I don't regret the things I've done, I regret the things I didn't do.

解析：一心在痛上，便无暇顾及他事。

We are so accustomed to disguise ourselves to others that in the end we become disguised to ourselves.

简单并非易事

创新不仅仅是技术的问题；它关乎改变人们的思维和生活方式。

做你自己；别人都已经有人做了。
