Badly/poorly organized people create more work for those who are well organized .

Planning is one of the things that are better learned by good example (not by reading a book); moreover people's innate capabilities in this particular task vary a lot.

That they are bad organized

There is method in the madness.

Well, speaking as someone who has always been a little "scatter-brained" [ meaning moving from subject to subject and thing to thing], I have never been very well-organized. I think Andrew's point is right. It's both something you learn from example, being shown how to be organized and it is varies enormously, which I think is determined by personality. What do I think about them? I think they are lovely people, especially if they are more disorganized than me and so therefore make me look good!
