A clean desk is a happy desk. In other words, the work space is no space for clutter. At the end of each day, I put everything in its place. I purge what I don't need and organize the rest. If you need paper trays and file folders to help you keep it together, then go for it. Whatever works for you, stick to it.
If you one complete one of these tasks on a daily basis, conquer this one. Make your bed every day. Your bedroom instantly appears in order. Making my bed puts me in the right frame of mind to start each day with a positive attitude. This is also a great chore to get your kids in the habit of mastering at an early age.
Our kitchen is the central command center. We have a drawer in our kitchen full of pens, clips, sticky notes, restaurant menus, etc. I like to hide that kind of "stuff" and keep the countertops clean. I also go through this drawer quite frequently to clear out the old "stuff" that can be tossed out. Believe me, it fills up fast, so stay on top of it.
I love baskets to stash almost anything and everything. Think of baskets as instant storage solutions for every room. I keep baskets in our closet to organize our belts, socks, scarves, and even shoes. We also have a couple of baskets in our den. At the end of the day, I pick up the remotes and magazines and place them in the appropriate basket for a clutter-free space.
You know how your mind wanders at night, thinking of all the things you need to do in the morning? Well. I have a tip to help you sleep better. Keep a pen and notepad in your bedside-table drawer. Before you go to bed each night, write your list of "to-do's" for the next day. Once you have written them down, you have no reason to keep worrying about "forgetting" them. This daily 2-minute task clears my head and gives me peace of mind. Try it and you'll see.
