But the angst begins to mount when the other actions on your lists are not reviewed and renegotiated by you or between you and everyone else. The constant sacrifices of not doing the work you have defined on your lists can be tolerated only if you know what you’re not doing. That requires regular processing of your in-tray (defining your work) and consistent review of complete lists of all your predetermined work. There are no interruptions—there are only mismanaged inputs.
