Make your apartment look peppy and lively by taking inspiration from Wake Up Sid, a movie which had great content, good cast and the decor was warm and welcoming. We are not suggesting you get a studio apartment but what you can try is painting one wall a different peppy colour, use some cool decals as per the space that you have. Practice or invest in some origami and you can stick or frame those on the wall too. Add a bookshelf and get some memories printed on a polaroid frame if possible. It would be an instant uplift indeed.
