Like someone mentioned above, you need to start treating villains like individuals and know that they are less good than you.
I would say this is misguided. You can't assume you're better than everyone at the table. It's important to identify who are good poker players, perhaps even better than you are. There's no shame in admitting there are people who are better than you. It's important we don't arrogantly assume everyone is bad. That is a mistake.
