Today I worked until I hit the wall. When you hit the wall you basically become unproductive. You don’t know what to do next and you find yourself staring at your stuff wondering what to do next. What you do next is you walk away for a while. If you push yourself at this stage you will simply end up having to do the work over again because you will do that work poorly. You will probably not make good decisions. Hitting the wall most often happens when you are having to make a lot of decisions—that happens a lot with paperwork and small items.
