When you are tired, hungry or angry. This should be obvious but often isn't. If you need to rest, sleep or cool down, postpone whatever it is that is preventing you from obtaining your basic needs. For instance, if you haven't slept more than four hours in the past day or if you are feeling ill, it would probably be a good idea to postpone any major decisions.The upshot is that there are circumstances when it's good to put off till tomorrow what you could get done today. Agree? Disagree? The Comments page awaits you. In the meantime, don't miss David's earlier post on productive procrastination. Photo by sjtodey.
