It is always good to have a problem that you cannot solve. It means you have something to work on.

If you don't make mistakes, you're not trying hard enough.

We have three baskets for investing：yes，no，and too tough to understand.

我不是一个喜欢平凡的人。

Ask anyone you admire: Their lucky breaks happened on a detour from their main goal. So embrace detours. Life is not a straight line for anyone.

We are constantly refining our models to improve performance.

我不害怕失败，我害怕不去尝试。
