永远不要，不要，不要，不要放弃。

The brain is not a computer in the traditional sense, but it does compute.

I don't know what the future holds, but I know who holds the future.

I love argument, I love debate. I don't expect anyone just to sit there and agree with me, that's not their job.

当别人拒绝你的时候，不要在意。假设他们和你一样：忙碌、没时间、注意力分散。稍后再试一次，很神奇，第二次尝试往往会成功。
