Artists at work and their work spaces

How do artists develop spaces and methods for making their most authentic work as part of a daily artistic practice?

In order to create the most effective and polished work, one must be in an environment where they feel comfortable and able to concentrate. This space needs to be their own. by this i mean, they make it their own by decorating, clutter, neatness, colors, plain walls, other works of art for inspiration, ect. Whatever the artist needs in order to feel most inspired and comfortable is how they will create their working space.
