If you're waiting for encouragement from others, you're doing it wrong. By the time people think an idea is good, it's probably too late.

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.

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.

The most customer-centric organizations can answer any question by deciding what's best for the customer, without ever having to ask.
