As a professional organizer, I find it much easier to tidy rooms and keep them organized if there is less stuff in the room. The less you have the easier cleaning will be. Also, having a cleaning routine will make the cleaning process a breeze, for example, setting two days in the week for vacuuming and dusting. Another tip is to adopt daily habits which help you keep your room tidy, like making your bed before you leave the room and not leaving any clothes on the floor or on other surfaces.
