A short but very important point that deserves its own chapter. From the "Eisenhower Matrix" section you already know how to sort tasks by importance and urgency. There's a whole group of tasks that are neither important nor urgent. To some extent household chores belong in that group. We also know that we should do important tasks first, and urgent ones above all. But sometimes we don't want to get started on those important tasks for all sorts of reasons — they may be very hard, the outcome may be uncertain (they might not pay off), or they may require stepping out of your comfort zone. In those cases we usually put them off and do all kinds of secondary trifles instead. Trifles that won't get us any closer to our goals.
Of course a big spring clean is a good thing, but you're doing it not because you planned it long ago, but because you simply don't want to get down to what really matters.
I call this laziness disguised as being very busy. I first came across that phrase in a book — I think it was "Rich Dad, Poor Dad", though I may be wrong. With the spring-clean example you're simply fooling yourself. You're too lazy to do the important things, so you do something else. And your main excuse is that this other thing is very important and that you're too busy right now to do anything else.
