You had all week to make that call, the one that has been on your to-do list for days. It only takes four minutes, but you keep pushing it off. It is now Friday afternoon; it is still on your list, and every time your eyes land on that item on your list, your stomach drops a little further. So, yet again you decide to push it off; you will do it Monday, when you are fresh. You immediately feel relieved, and for about an hour that relief holds.
