In a perfect world your master bedroom should be a haven in which you and your spouse can retreat from the world and enjoy each other. Unfortunately, the same type of clutter and dust that invades every other room in your house can spill over into your master bedroom.
One of the easiest ways to spiffy up your master bedroom on a daily basis is make the bed. It's a simple as that. If you aren't someone who routinely makes the bed you'll be amazed how much better a room will look and how quickly you'll be hooked. A great facelift for a bedroom is also a simple one, it's called a "bed in a bag". These sets come with comforters, coordinating sheets, pillow shams and bed skirts. If you have a visible bathroom attached to the master bedroom it's nice to carry your color theme through to the bathroom too.
Clear off the top of your dressers. As with all flat surfaces these will tend to gather papers too. If you don't have a home office where you keep bills and other important papers, get an organizer. A good way to organize bills and papers is in an accordion folder. They can be organized alphabetically or by month. Just get them off your dresser!
