Negative people.
People who just say whatever they want without caring about your feelings.
People who do whatever they want without thinking of the impacts of their actions to your feelings.
People who won't stop whining about their 'miserable life'.
People who get jealous and angered easily.
People who sweat the small stuff.
It's time to keep yourself away from those people and surround yourself with positive people.
Now imagine, if you're really doing that, just exactly how many people would have left?
Just imagine.
