I noticed that if I spent a day where I experienced three hours of flow early on, for the rest of the day, I felt relaxed and open and able to engage to walk along the beach, or start chatting to people, or read a book, without feeling cramped, or irritable, or phone-hungry. It was like the flow was relaxing my body and opening my mind -perhaps because I knew I had done my best. I felt myself falling into a different rhythm. I realized then that to recover from our loss of attention, it is not enough to strip out our distractions. That will just create a void. We need to strip out our distractions and to replace them with sources of flow.
