LOVE this! Need to remember to this myself. Our room has all the storage and clutter and it's just a plain disaster.
My bedroom is the cleanest/tidiest room in the house. I make a promise to myself to keep it this way when my kids were very young & I was exhausted from little sleep/busy schedule. A beautiful serene room sets the tone for you when you wake up in the morning & when you fall asleep. When life gets hectic I always say to myself, "at least the bed got made today' and my room is clean.
If you have the mind set that your bedroom is an oasis and there is not an exception to this rule, it will help you keep it serene. Remove everything that needs to be taken out of your bedroom and find another home for it. Tidy your bed every morning and make sure your floor/furniture is clear before you go to sleep.
Use the other awesome suggests too. You deserve an oasis. Don't let it be a place where you dump things.
