Owing to my upbringing and my parents, I often used to frown upon other people who would not fit into my narrow worldview or would not live up to my standards. This included (inferior) job positions, clothing, hair styles, furniture, and much more. All of this in a seeming attempt to elevate my brittle ego (I was suffering from a narcisstic personality disorder back then).
Thanks to the development of a more tolerating and healthier consciousness over the last few years, this has slowly but surely changed. I now can look at others and appreciate their differences instead of condemning them; I learned that each and everyone of us is a part of the grand mosaic of creation. How boring it would be, if human beings were all the same.
Thus, embrace the variety!
