4. You ask questions, but don't really pay attention to the answers.
You know the type of person I'm talking about. They ask for your opinion, but they're only really interested in what you have to say if it's exactly what they already believe. That baffles me. These kinds of entrepreneurs surround themselves with people who will only ever agree with them. That's bad for business. You'll make better decisions if you abandon your stubbornness, truly weigh different points of view and try to understand other perspectives.
