Is it a disorder to find most people uninteresting?

I wouldn't find it to be disorder necessarily. I honestly couldn't agree more, funny I come across this today as I'm feeling the same way. Unfortunately what it comes down to is quite simple.

Less than 40% of Americans have a passport and perhaps only a tenth or less of that count have traveled outside of the U.S more than twice to two different countries outside of (US/Canada/Mexico). So imagine, like you said, sheltered people living on a meager income living a meager life leaves people being dreamless robots!

You've tasted the freedom, seen people struggle in 3rd world countries, met different cultures perhaps and interacted with them more than a hi/bye basis - it changes the wiring in your brain and its hard to settle.

I myself struggle with making friends. I find many people shallow, dreamless, no goals, no aspirations or fulfilled dreams (although many have dreams and don't fulfill even one of them). Has nothing to do with being narcissistic.

But it doesn't make it better to sit there and complain, go out there and find where you belong, chances are many people don't even feel like they belong themselves and are overridden with insecurities.

I recently made friends with someone I met while I was abroad and they quickly became one of my best friends. There's still hope! Don't lose faith in trying to reach out to people, if they turn you down - its probably for your best interest. Get out of your comfort zone if you are truly interested in having the slightest chance of meeting that one new friend that will keep you going.
