You really need to spend a lot of your time focussing people.

Force yourself to simplify every initiative, every product, every marketing, everything you do.

I walk into a company office and I can tell often whether I'm gonna invest, as soon as I walk in.

At first when you start a company, everything's gonna feel like a mess and it really should. It should feel like everyday there's a new problem, and what you're doing is fundamentally triaging.

The next thing you do is allocate resources.

The key metric of whether you've succeeded is what fraction of your employees use that dashboard everyday.

There are three things you need to do as a CEO-founder. Think strategically, drive design, and drive technology. Some people who are really good at one can build a pretty foundational company. Most people who are very successful are good at two. But Jack is the only person in the Valley I've met who's all three. He's a first-rate strategist, a first-rate designer, and a first-rate technologist.
