Decorating bedroom..too many ideas..help me decide?

I want to decorate my bedroom, but I like too many different styles and can't narrow my ideas down. Would love to live in a little stone cottage in England, so thought of wallpapering with stone type wallpaper (and what else?); Already have a very nice comforter with a beautiful deep colored tropical scene (maybe bamboo, etc.); Thought of just doing blue and white (quilt, small white linen covered reading chair, blue walls); and on and on. At this point my brain is spinning. Any ideas? Thanks
