How do i decorate my room?

Well it depends on what you like. Some ways to do a room makeover is painting your room a theme you like or putting up posters and pictures of people you like. For example-- if you like sports you can hang a Basketball hoop above your bed and put up sporting type posters. If you have medals and diplomas you can hang them up. In other Words, making a room makeover has lots to do with how your wall looks. Its nice to show of things you like in your room and it also gives a nice feeling. Tidying up your room also helps a lot. So, have fun.

Answer

If you cannot visualize the room differently, first empty it. Clean the walls, fill in the holes and paint and clean the flooring. Then, add back the bed and basic furniture. Once that is arranged, bring back items that seem to fit. Throw away or give away the rest--storage of these items is not wise in the long run (they get ruined), and you will probably never use them again. You can ask siblings or friends if they want the leftovers. Things will seem new in your renovated space.
