A mistake is only an error, it becomes a mistake when you fail to correct it.

A mistake is to commit a misunderstanding.

A man who has committed a mistake and doesn't correct it is committing another mistake.

I make plenty of mistakes and I'll make plenty more mistakes, too. That's part of the game. You've just gotta make sure that the right things overcome the wrong ones.

Almost any mistake you can make in running a company, I've probably made.

When I'm introspective about the last few years I think the biggest mistake that we made, as a company, is betting too much on HTML5 as opposed to native... because it just wasn't there. And it's not that HTML5 is bad. I'm actually, on long-term, really excited about it. One of the things that's interesting is we actually have more people on a daily basis using mobile Web Facebook than we have using our iOS or Android apps combined. So mobile Web is a big thing for us.
