Paradigm Shift.

An old friend once said, (what could have been the BEST advice i've ever been given)

'if people do nasty things to you, act like you don't give a shit'.

why waste time and energy stressing over whether these people like you or not. their opinions shouldn't even matter. so, to my friend (who shall not be named here), my advice to you is...

Choose not to give a rat's ass.
