Did you know there are some things or people who are bad for your general well-being and existence and that they should be gotten rid of too? I'm sure you know but my main focus on this post will mostly be on the people who are generally bad for you and yours.
I've heard series of stories from TV, radio, other people, even read on the newspaper of how people treat others who they are supposed to be friends with but because of greed, jealousy, envy, backbiting and even hatred, they treat them like they are less human. These kind of mean people make their victims think or feel small of themselves . People like those are called toxic and they shouldn't be around clean or sane people.
The best way to treat these category of people is to cut them off from your life, completely. There's no reason to keep such toxicity around. Severing every toxic relationship will contribute to you having more productive time to do and be at your best.
