I think you must have your own office. I don't believe ever in shared office spaces.

Transparency people talk a lot about, it's a goal everybody ascribes to but when push comes to shove, very few people actually adhere to it.

Any executive, any CEO should not have 1 management style. Your management style needs to be dictated by your employee.

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.

You can build the most important companies in history with a very simple to describe concept. You can market products in less than 50 characters. There is no reason why you can't build your company the same way. So force yourself to simplify every initiative, every product, every marketing, everything you do. Basically take out that red and start eliminating stuff.

The next thing you do is allocate resources.

The people that work with you should generally come up with their own initiatives.
