I read so many times of this word recently. You know, when you get to much exposure of negative things, you may start to think or act negatively. Seems like the words can go into your veins and remains in your brain cell so that they can control you. Ok, this is just my imagination and there’s no logic reason behind it. But still, I don’t want “err” controlling me. So, I decided to let a positive word go into my veins and fight against it.
