A thousand times this. Life is short, don't work with assholes, and more appropriately, don't work with people you don't respect and enjoy.

In larger companies you have to work with people you respect but don't like. Don't do that in a startup, it takes away the passion and the motivation.

This is the mistake everyone makes. Don't think in terms of someone being an asshole (unless it is you). Think in terms of chemistry.
