The only thing worse than a liar is a liar that’s also a hypocrite.

The wisdom of hindsight, so useful to historians and indeed to authors of memoirs, is sadly denied to practising politicians.

"I don't think about the past. I focus on the present and the future."

我认为人们相信天堂是因为他们不喜欢死亡的想法，因为他们想继续活着，他们不喜欢别人会搬进他们的房子并把他们的东西扔进垃圾堆的想法。

无人机的未来在于垂直领域的深耕。
