There are different types of conflicts some of which can be treated with this type of thinking. If procrastinating doesn't feel worse than working, then your mental conflict is of different type. (I personally can relate to what EY is talking about.)

The bigger problem is that, depending on the type of conflict that causes the procrastination, the brain is very resistant against these types of insights. The insight works for a short while and sooner than you realize (or to be more exact, don't realize), your brain finds a way to side-step this trick.
