Three things. 1. Not everyone is created equal. Not everyone has the same experiences. If you are smarter or more wise, realize that they are stupid without malice or disdain. If you are the stupid one, listen to what they have to say. Wheb you realize people are dumb but don't hold it against them their opinion doesn't matter. 2. Nobody cares about you. Everyone thinks their actions and influence is greater than it is. You are the primary character in your story. Everyone else is secondary. Those people feel the same way about you. You simply aren't as important to then as you think, and that's a good thing. Who gives a fuck? Nobody. 3. Remove emotionality from yourself. Having feelings is great. Allowing feelings to make any action or influence actions whatsoever is stupid. Wheb you can say you make every choice from logic and thought then you will realize most people don't. And that's ok. But it also makes their opinions useless.
