When you start a company, it's more an art than a science because it's totally unknown. Instead of solving high-profile problems, try to solve something that's deeply personal to you. Ideally, if you're an ordinary person and you've just solved your problem, you might have solved the problem for millions of people.

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

The second thing I had to do was not to be reluctant as a leader...And when I started doing that, I realized that people are thriving from this, and that it's so much more helpful for people.

Culture is simply a shared way of doing something with passion.

Somebody asked me 'what's the job of a CEO', and there's a number of things a CEO does. What you mostly do is articulate the vision, develop the strategy, and you gotta hire people to fit the culture. If you do those three things, you basically have a company. And that company will hopefully be successful, if you have the right vision, the right strategy, and good people.

The stuff that matters in life is no longer stuff. It's other people. It's relationships. It's experience.

[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.
