I have a question regarding my studio apartment?

How do I de clutter a studio apartment? My husband and I recently moved into a studio apartment to save money and that was a good thing, but we have piles of paper and things on our table where we eat and picture frames on the floor and books and photo albums as well, in addition we did a tiny bit of decorating for Christmas as well, we put up a very tiny glitter tree and Nativity and on our shelf we put a couple of ornaments. Have any of you lived in a studio and what did you do to de- clutter and make everything more organized? Thank you in advance for your answers.
