I want to share a little story with you:
Today I met with a friend in a café to talk and to eat something. At the moment its very cold outside where I'm coming from and the café had a very good heating. So when we sat there I recognized a young man coming in and my first thought was that he was a cool looking dude - very well/stylish dressed, wearing a red beani, and I thought he surely knew how good looking he was. After a while he took his beanie off and you could clearly see thinning hair - especially his crown. he was nervously trying to get his hair into shape - and then the next time he decided to put the beanie on again
from this moment on I saw him with different eyes, just because his self-consciousness was so clear to me, he could have definitely pulled off the bald style and if he would have acted confident I wouldn't even have thought of him as an unconfident guy
so the moral of the story is: we think way to much about how other people might perceive us - and with this mind-set we might influence the perception quite negatively
and everyone seems to be so much occupied with his own fears and imperfections that mostly no one seems to notice those you think you have yourself
