Wow man !! That was a good read. You thought pretty deep about it.
But it can be tackled easily with practice.
I remember those times when i used to think how awkward a situation was when i did that or this but then i thought, would those people be remembering it as many times as i am? Would they be thinking about how dumb or clumsy I behaved !!! Of course not. They might not even remember it when they meet me next time. So i practiced and stopped thinking about the bad things coz they don't do anything accept making me sad and negative.
Nice post !!! I post about the same things like psychology, philosophy etc. I loved it :)
