"Organized" is by definition systematic. It’s not possible to be organized without some sort of system, and usually it’s a game plan made up of multiple systems that work together to give you your overall level of efficiency.
If you feel the need for more organization in your life, what you’re actually yearning for is one or more systems. Sure, you might chafe at the idea of having to actually follow that system, but it really is what you want and need. You might not like the idea of following a system, but you’ll appreciate the end result.
The trick to not feeling as if you’ve given up control is to write your own rules. Don’t do what some professional organizer says just because she’s supposed to be an expert. Don’t just passively adopt someone else’s system word for word. Instead, make it your own. Adapt it to your needs, preferences, tolerances, and priorities. Requirements that are imposed upon us can be intolerable; parameters that we establish for ourselves are a disciplined way to expedite the accomplishment of our goals. THAT is why they’re good for us.
