Pick one area that needs to be organized/decluttered/purged. I am going to pick the medicine cabinet. Have a trashcan ready!
First: Take everything out!
Second: Sort through the mess; throw away anything old, expired, or unusable.
Third: Look at the remaining pile and double check to make sure that you need everything.
Fourth: Put things back. Make sure you can see everything, so you know what you have.
In 15 minutes, you have just done a fantastic job of organizing!!
