The next time you catch yourself judging someone for their clothing, hobbies, or interests ask yourself “what does it matter to me?” The more you train yourself to not care about the personal preferences of other people, the more relaxed you become. You become a nicer person
Bonus if you can ask yourself why you’re judging someone, it may help get to the root. We all like to make connections & associations but if you drill down to the “why”, you can really start to address the implicit biases.
if you believe that, you miss a few decades of history in your knowledge ..
but then what's the point of arguing ? :)
