A different explanation for procrastination—one which can help overcome it—is that when we procrastinate we're self-deceived about our preparedness for the task; we inarticulately perceive that doing the tasks out of order would harm the product.

Yes! Yes, yes, yes.

This is exactly what I've experienced myself. When I'm procrastinating on a major piece of code I need to write it's almost always because I am uncertain that the structure of the code I've decided on is correct, or, worse, that the subsystem the code is for is itself an unneeded or misguided component of the final project.

When I have a laundry list of things to code and I am confident that all the items are necessary and properly thought out I am more motivated the longer the list!
