It works like this: You want to get started with grading that stack of papers, you really do. But you also want check your facebook page and generally waste some time on the web. Certainly the reward for getting those papers graded is greater than the reward of finding out what your acquaintances ate for lunch...but it's so far in the future. It's too far in the future. And it requires a feat of imagination (and the hippocampus) to fully and richly imagine that distant reward enough that it feels tangible and worth working toward.
This problem is exacerbated when the distant reward we're talking about is for finishing a dissertation or a book. That's months away. Years away. Too far away.
The take home here, as I see it, is that mini-goals are still the way to go: narrow the gap between now and gratification by giving yourself a mini-goal. But, also, try vividly and imaginatively conjuring up that far-distant reward. What will it feel like to be done? What has a similar situation looked like and felt like in the past? Make it real for yourself. This might just make that distant reward feel gratifying enough to get started!
