I don't really get the personality piece...do mean that you're not "born organized" like some people who seem to magically be able to sort and organize and seem to enjoy it? That you are more creative? If so, check out flylady.net. MamaMay's post below alludes to Pam and Peggy and Flylady grew out of that.
I think I may have more "born organized" tendencies than not, so some things about Flylady drive me nuts and I think the design of the website is awful, but the overall approach is very helpful. Her main mottos include gems like "progress not perfection," "you can't organize clutter you have to get rid of it" and "you are not behind, I do not want you to catch up, just jump in where you are." Perfectionism is looked upon as a character flaw and something that must be gotten rid of, which is a nice way to approach getting and staying organized - it's a daily process of making things better in baby steps, not a quest that ends with some magical, unattainable state of perfection.
