How should I do this????????????????????

Well right now I have grey, white, and light blue speckled formica furniture which I am keeping. My comforter is grey with royal blue trim. In the dead center their is a patch with the New York Mets symbol. The symbol is orange, white, and blue. Then I have a fan in my room that is grey and has sliver and blue gl around the light bulbs. Right now my walls are light baby blue which I hate, and a darker baby blue carpet with white molding. I have these weird curtains that have sport on it and these matching pillow cases which I hate. What should I do to actually enjoy my room? What colour walls what colour ceiling what colour curtains and pillow cases?? I am a boy by the way.
