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.

Basically take out that red and start eliminating stuff.
