Don’t expect to see positive changes in your life if you surround yourself with negative people. Don’t give part-time people a full-time position in your life. Know your value and what you have to offer, and never settle for anything less than what you deserve. - via: http://www.marcandangel.com/2012/05/23/14-rules-for-being-you/
In more ways than one. When your life isn't going smoothly it will reveal them, and when their lives aren't as smooth either. I've had people jump to treating me poorly because their choices weren't doing any favors for them, and no matter how much I just tried to be there I had to repeatedly tell them I wasn't a whipping post. Too bad they didn't understand before I had to cut them out.
