Eh, not everyone thinks the way you do.
I have similar opinions and ideas. My mother always pushed me academically and never, ever conceded that I did well, no matter how well I might do. Around High School, I stopped giving a f***. I came to a realization - onlyyou can shatter your self-confidence.
Everyone on these sites has an ego. Yes, we've all been in that place where we were convinced we were the smartest, strongest, fastest, best looking dude on the planet. Fact is, that was never true.
So if that idea was somehow "shattered," it's really only because you've allowed it to be shattered. People on these sites call it self-esteem issues, I call it facing reality. You may be smarter, taller, and better looking than the average bear, but you were never all that like you thought when you had that God complex as a teenager. Your still the same person, just older, wiser, and more realistic.
Because you're losing your hair does not make you any less of the person you once were, nor has it stripped you of your youth. Guess what? Soon your skin will start wrinkling, your muscles will hurt more, your joints will ache, and eventually, you won't even be here. Worrying about it solves nothing. Life strips you of your youth, not hair loss. You're not going to be 20 forever, and you've just got to accept it.
That's how I see it. Not everyone will agree, but then, people are self-indulgent.
