My grandfather was an autoworker, and I have a weapon he manufactured to protect himself from the company that he would carry to work. It's a big iron pipe with a hunk of lead on the head. I think about how far we've come as companies from those days, where workers had to protect themselves from the company.

Computing is kind of a mess. Your computer doesn't know where you are. It doesn't know what you're doing. It doesn't know what you know.

You don't need to have a 100-person company to develop that idea.

You need to get one thing done well, or else you don't have permission to do anything else.

Always work hard on something uncomfortably exciting!

For a lot of companies, it's useful for them to feel like they have an obvious competitor and to rally around that. I personally believe it's better to shoot higher. You don't want to be looking at your competitors. You want to be looking at what's possible and how to make the world better.

I think it is often easier to make progress on mega-ambitious dreams. I know that sounds completely nuts. But, since no one else is crazy enough to do it, you have little competition. There are so few people this crazy that I feel like I know them all by first name. They all travel as if they are pack dogs and stick to each other like glue. The best people want to work the big challenges.
