For me, work and home have wildly different cadences. At work, I am in the zone. 20 places at once, solving problems for people, answering questions, counseling the grief stricken disgruntled, inspiring the new employees. Killing them softly with my song. 90% of my week is not at my desk. I am in flow most of my day. I am ON.
At home, I try to defrag and relax. I play tennis with the kids and watch them play music. (guitar, drums, bass, etc) I read. We eat. The pace slows down. This is when my mind processes all of the information of the week. I am OFF. It focuses me. My mind becomes sharp. I am ready for a new day.
It is tiring to be ON for long periods of time. This is why people need downtime and vacations. This is why people need escapes, like watching football or playing games. Being ON gets the best out of people, until they run out of gas.
It would be cool to see how many minutes or hours someone spends being ON versus OFF. We could have a contest. I imagine that politicians are ON most of the time they are in public.
