What I've been surprised by is not how different people are, but how similar they are. There are certain types of Airbnb people, and they are in every city in the world - it's just that in some cultures, there is more of a generational divide.

Everyone's got a moment or two in their life where something happens and you make a decision and then your entire life changes.

Do things that won't scale; it will teach you.

The stronger the culture, the less corporate process a company needs. When the culture is strong, you can trust everyone to do the right thing. People can be independent and autonomous. They can be entrepreneurial.

Build something 100 people love, not something 1 million people kind of like.

[On culture] It's living the core values when you hire; when you write an email; when you are working on a project; when you are walking in the hall.

Whatever career you're in, assume it's going to be a massive failure. That way, you're not making decisions based on success, money and career. You're only making it based on doing what you love.
