技术本身没有好坏，关键看你怎么用它。

Don’t wait until they tell you you are ready. The world might say you are not allowed to yet. I waited a long time in the world before I gave myself permission to fail. Please, Don’t even bother asking, don't bothering telling the world you are ready. Show it. Do it.

Quality is not something you can add on to a product or service. It must be built in from the beginning.

最好的数学不仅严谨，而且优雅。
