What business do negative people have in your life? Why are they there in the first place?
Because you let them hang around. Could it be you hang around them?
What happens when you are surrounded by even just one negative Nellie?
Your whole day, attitude, perspective, and direction changes - for the worse. Before you know it there's a pattern that goes like this: "I know she's negative but she has some good qualities, too." Then, "I can fix her negativity." Next, "She really isn't THAT negative." Lastly, "What? She's negative? I didn't notice."
