Why Unfocused Attention Leads to Anxiety and Stress

Our daily lives can be OK – good enough job, we have friends, we do our best to lead a healthy lifestyle etc. Yet we feel stressed-out and depleted at the end of the day. Or even before noon. We all have such out of control days. Like we are just along for a ride on a mad rollercoaster. While other days we are firing on all cylinders all day long and are still full of energy and ready to go in the evening. Why is that so? And how can we have more of the latter days? The clue lies in figuring out what makes other days so full of energy and enthusiasm. What is so special about them.
