How do you get a piece of mind
Learn that we all are human, perfection does not exists and find ways to let go of what troubles you! Even if it means simply watching reruns of some stupid childhood show to make you ease your mind for a bit.
Do you "a piece of my mind" or "peace of mind"? Pretty different things!
take out your brain, get a knife, and start dicing!
Just ask for it, I'm sure someone will give you a piece of theirs! :)
By staying away from people who do not have it.
