First off, Nice post. But I disagree slightly out of experience from my own toils with procrastination. I find that I, among many other humans simply want to remain in a state of comfort, whatever that means to each person. Every little thing that deviates one from constant comfort becomes a bump in the state of mind, this bump can be smoothed out in 1 of 2 ways, You can do what you should do, the task at hand, or you can put it off in exchange for a moment of instant gratification, or some distraction action. Now in behavioral theory, there is much less mental strife or tension involve in procrastination (initially), and if the competitor action to inaction a mentally or physically longer journey requiring more energy to complete, the natural response would be the shortest of the two. Instant gratification is powerful! Its a tug-of-war calculation between actions, we will do whatever we can do that's easier or more enjoyable unless we fear the outcome of inaction so much so that it out-ways the positives of the other. We are fundamentally powerless against this. For all you fellow entrepreneurs out there, we simply love building things more than anything else. My procrastination for example consists of working on projects or prototyping a new app. I will default to that when countered with options of going to the movies, eating out, or playing video games. One could argue however that fear of failure motivates one above all others to strive for success. Just my 2 cents.
