This is a very good comment. I feel like this point is not appreciated enough. I've been in on meetings where people get very passionate about the subject under discussion. I have seen people become stubborn. I have seen people lose their temper. I have seen meetings drag on for 5 hours. Yet usually the subject under discussion did not deserve the intensity with which it was discussed. Even when a subject is very important, in a startup, we often have to deal in a vacuum of data, so why fight, when really, neither of us can be sure of our position? Why not just move passed the issue and come back to it 3 months later, when more data might be available? People underestimate how expensive time is. This is especially true in a startup. And the less people are paid, the more this is true - people underestimate how expensive it is to spend time discussing X, when we could be doing Y. Everything has an opportunity cost, but these are hard to see.
