The ‘edge’ has been rubbed off? I’ve always been able to either focus hard – or be incredibly distractible. When I was distractible – I had coped by using an almost addict level of control to ‘get’ myself to focus through habit or strong arming myself. I’ve had to do what is needed to get things done. Now, I have more of a choice in the moment – to focus, take a break – commit to something etc.
