Let me ask you something. Have you ever laid in bed at night and your mind just would not stop? You think about that thing you said at work. You think about that money problem. You think about what people think of you. And sleep just runs away. This happens to so many of us. It happens to me too sometimes.
I have spent years trying to figure out why our brains do this to us. Why do we hold onto bad stuff so easily? Good things happen and we forget them in five minutes. One small bad thing happens and it stays with us for days. This is not your fault. This is how human brains are built. But here is the thing. You can change it. You really control negative thoughts.
