I think this is terrible advice. I got much better at motivation over the last year by thinking in exactly the opposite way from what this article recommends. I accepted that I had virtually no willpower, and that I wasn't just going to just magically develop some, and that I didn't need it anyway. Instead I needed to get more skilled at 'coaxing' myself into doing things – at steering my feelings into more constructive areas, and then letting my desires drive my actions. I applied my tiny amount of willpower to this 'steering', rather than trying to use it to drag myself kicking and screaming into doing things, which it clearly is not powerful enough to do. It worked, and I'm much happier. You can't "just" do stuff if you don't feel like it, as this article suggests. That's completely unsustainable. Any approach amounting to "just fucking do it" is going to last only as along as that little glimmer of resolve lasts, which is obviously short term. Instead you need to break down the wall between your gut desires and your cerebral strategies, and make those two parts of yourself acknowledge each other and collaborate.
