Well said. I think you need a little swagger to handle the overwhelming odds against you as a startup. What you don't need are assholes.

There is nothing wrong with a little swagger, or confidence. However, adopting "no assholes" isn't quite enough: a non-asshole can still let their ego get in the way of their work and their team. For example, by refusing to admit fault.
