René Descartes once wrote, “I think, therefore I am.”  It’s a phrase most of us have heard, but it carries so much weight when it comes to mental health. What we think shapes what we see. And what we see, we come to believe as truth. Take for example the thought: “I am a failure.” When that thought takes over, it’s like putting a filter on a camera and locking the zoom lens on one small detail. Suddenly, every part of the picture seems to confirm the belief. A mistake at work
