I don't use many apps. I use naps.

I tend to not discriminate when it comes to people I can learn from. Basically, if someone has built a meaningful business in software, technology or media, faced disruption and adversity, and overcame underdog status, I want to know how they did it.

Focus too much on the near-term and you won't get tomorrow's customers, focus too much on the long-term and you won't get today's.

The chance of failure is almost always better than the guarantee of never knowing.

You'll learn more in a day talking to customers than a week of brainstorming, a month of watching competitors, or a year of market research.

My mom is proud of me. But she might not be too happy about the hours I keep or how little I eat. I wake up so late that it would be inappropriate to have breakfast. At most, I will have a snack in the day and dinner. I realize that it's not the healthiest way to live, but it's all I really have time for.

I think people are always able to achieve more than they think they can. While that’s cliche, I don’t know if managers think about that enough. You have to set your sights extremely high.
