Structured procrastination is a term coined by John Perry. In his words, the structured procrastination is about using one character flaw (self-deception) to offset the bad effects of another (procrastination).
To put it simple: You have a task at the top of the list that makes you worry, but you procrastinate about doing it. Rather, it motivates you to do other, also useful, though maybe less important, tasks, as an excuse for not doing the unpleasant task at the top of the list.
You end up accomplishing few things, and that is the goal. You might not have come to that task sitting at the top of the list, but who cares. Something even more important, pressing and unpleasant might emerge very soon, causing you to do that task as an excuse for not doing the new one.
The proposed trick that makes this method more useful in real life, is to choose the right sort of tasks for the top of your to-do list. Best candidates being those SEEMINGLY having deadline and big importance, but where in fact nothing happens if you don't accomplish them on that deadline.
Structured procrastination is about not doing the seemingly important tasks from the top of your to-do list as a way to rather work on the less important tasks from the middle of your to-do list.
If it works for you, use it. I wouldn't recommend it if it feels unnatural to you, because in my eyes, anything based on self-deception is just another bad habit to make, where one would rather end up replacing bad habit with good habit. Anyway, structured procrastination is still better than plain procrastination, and might fit your working habits, so why not give it a try.
