创业的路上，困难和挑战是不可避免的，但正是这些困难和挑战让我们变得更强大。

The mind， both in so far as it understands， and in so far as it imagines， is passive.

The great powers are always searching for opportunities to gain power at the expense of their rivals, and they will use force if they believe it will bring them strategic advantage.

I believe in the power of positive thinking.

不管你认为你能，还是你认为你不能——你是对的。
