This actually happens a lot more than you think and to many more people than you'd imagine. It is a common epidemic that actually might be rooted in something deep inside you. Take note of why you are feeling the way you are when procrastinating. Maybe it is because you simply don't like the project and are forced to do it for one reason or another. Maybe it is because your mind still hasn't fully formed the ideas that you intend to put out there. This descriptive difference may lead to a new word being used to describe your situation rather than procrastination. That word is gestation.
Whatever you are working on isn't fully formed and needs time to ripen in your mind.
The important difference between procrastination and gestation is willpower. While you are gestating, you are intentionally taking a break from your work in order to fully form your thoughts. While you are procrastinating, there is constantly a little voice inside your head that is nudging you to finish your work.
Best way to combat this? Decide right here and now that you will continue procrastinating for the next five or so minutes and THEN you will do your work no questions asked.
By allowing yourself a break, you can actually fully relax and enjoy the time you have. What often happens is when you are procrastinating that you are in a state of half-relax and half-stress knowing that you must get the work done. Take control and make intentional use of your time.
