it depends on the seriousness of the appointment, but mostly it feels like if i start something else in between i wouldn’t have enough time to finish the task, i might get sidetracked and totally overwhelmed and everything is just stressful. even if it’s an easy and everyday task i’m doing in between, i’m suddenly feeling a lot of stress and pressure. so to some extent it’s bad time management due to getting sidetracked, fear of failure and that combination leads to radical time management: don’t do any task before! and for similar reasons the time afterwards is also somewhat uncomfortable
