Case in point: a few years ago, I noticed that my hair wasn't quite as thick and lush as it once was. I panicked, stupidly. Without performing adequate research, I began taking a medication that blocks the hormone DHT. Only later did I learn that this medication can subtly alter cognition by affecting the production of various neuro-steroids. Obviously, the value of my mind vastly outweighs that of my appearance, so I stopped taking the medication knowing that one day, I'd probably lose my hair because of it.
Despite the obviousness of the choice, it was ridiculously difficult to implement. The social imperative to be beautiful is powerful. Yet:
You aren't your hair. Or your face. Or your breasts.
It may very well be that attractive people have it easier than less attractive people. But that's a problem with human nature, not with those not blessed by beauty. Make reasonable steps to improve your appearance, then forget about it. Self confidence, humor, and a compassionate nature will always win the day with people who matter.
Ask yourself: is Steve Jobs as classically attractive as Brad Pitt? Who is more accomplished? Isaac Asimov? Donald Knuth?
