No ... we don't want you to get rid of all your stuff!
One of the first things we share with prospective clients (both organizing and downsizing) is "you can and should keep the things you LOVE, it's the stuff you LIKE that we may need to talk about". While it may seem like a very simple statement, it's a very helpful thing to talk about when you're starting to think about getting things organized (whether you're staying where you are or transitioning to a smaller space). This statement is an important way to build trust with a client but can be just as effective if you're getting ready to do the work yourself and want some confidence in what you're about to undertake. So much of the focus of organizing is about what you get rid of that, for many people, it's a very negative and scary proposition. As much as we may wish that our living spaces were neat, clean and organized, what often stands in the way of that is the fear of letting go. So, start off by establishing some "ground rules" with yourself, your family or your organizer so that you can get the process started without all the negative emotions that are getting in your way.
First off, you'll surprise yourself in just how much stuff you WANT to get rid of. You haven't seen much of what's in your house in quite some time. Don't believe me? Open the bottom drawer of your desk or bureau, look in the back of a cabinet or closet. You'll find things you hadn't thought of (or needed/wanted) in quite a while.
The real point to getting organized isn't to get rid of stuff, it's to highlight the things you love and need. Even the most organized people have things ... lots of things. It's just that they (generally) only keep things that have meaning or are useful. By focussing on those things (and getting rid of the rest) they're able to enjoy the things they have and the home that they live in.
