It's such a simple thing but why do most people NOT do it? I love my husband. He makes our bed every single day, whether he's late to work or not. I really appreciate it and I have to say, it makes SUCH a big difference in my day.
Have you ever noticed that when the bed is made, you want to keep the rest of the room tidy as well? BUT, if the bed isn't made, you ignore everything else in the room.
Then, if the bedroom is clean, you start to notice when the other rooms aren't and you're more likely to just quickly pick up those rooms as well. In my house, the tidy room seeps in to the rest of the house and I feel way more productive.
Though my teens haven't quite picked up on this wisdom, I'm hoping that one day it'll click. I can hope, right?
Side note: there is nothing more satisfying then being able to get in to a nicely made bed at the end of the day. It feels like you've really earned the rest.
Try it for a week and see. Trust me.
