每把锁都有钥匙，每个问题都有解决方案。
Every lock has a key, every problem has a solution.
You think it will never happen to you, that it cannot happen to you, that you are the only person in the world to whom none of these things will ever happen, and then, one by one, they all begin to happen to you, in the same way they happen to everyone else.
实现不可能的唯一方法就是相信它是可能的。
Nothing is certain， and nothing is impossible.
If you’re not moving forward, you’re falling behind.
