How to self-destruct 101. 1. Create an opportunity to screw up, 2. throw your brain out of the window and do something anyone would call stupid, while taking on that opportunity. 3. Fail. Congratulations. You're done.
Whenever I wake up in the morning, first thing I do is to run to the next mirror and do a self-check. "Yepp, still handsome." ... Firstly sometimes people, even those who are on the handsome side, might be socially awkward. They might not notice, even if they are handsome. When they are socially awkward, chances are, they have self-esteem problems. Okay, next: Try to imagine you wake up in the morning and still look the same like the day before. Shouldn't be too hard. In most cases you know your own face as you see it nearly daily. You aren't really in the position to judge, if you are attractive or not. Sure, you can say cute nose, fierce eyebrows, gentle eyes, lustful lips ... what ever, but in most cases your aren't really attracted to yourself. So how can one expect from others to truly judge their own charm-levels? With feedback from other its no problem, but without...well, try to guess how the sky tastes.
