It is a never ending list.
My environment is very important to me. My surroundings (sight, smell, sound, "feel") are constantly being manipulated to be the most pleasing to me.
I either have or am working on floor to ceiling curtains, candelabras mounted on all the walls, an epic sound system (since my music means so much to me. It's practically a religion in itself.)ect. But it will never be enough. When I am done on the inside, I will complete the outside, and out as far as my might can reach for my ideal environment. But at least for now, I have my little enclosure.
