You can't be focussed without really great communication

Another way of looking at this, is that the best companies are almost always mission oriented.

Every thing at a startup gets modeled after the founders. Whatever the founders do becomes the culture.

The best people know that they should join a rocketship.

The second part of how to hire: try not to.

It's difficult to get large groups of people, to the extreme levels of focus and productivity that you need, for a startup to be successful.

The best ideas often look terrible at the beginning the truly good ideas, don't seem like they're worth stealing.
