生活是记忆与遗忘之间永无止境的斗争。

不要让自己成为别人的影子，要敢于做真实的自己。

你以为早上醒来昨天就不算数了。但昨天才是真正算数的。

Success isn't owned, it's leased, and rent is due every day.

Risk management in mining isn't about eliminating all risks - that's impossible - but about understanding and mitigating them intelligently.

What I think I've been talking about really is success and failure. And one of the interesting things about success is that we think we know what it means. If I said that there's somebody behind the screen who's very successful, certain ideas would immediately come to mind. You'd think that person might have made a lot of money, achieved renown in some field. My own theory of success -- I'm somebody who's very interested in success, I really want to be successful, always thinking, how can I be more successful? But as I get older, I'm also very nuanced about what that word "success" might mean.
