Whenever a bulb burns out and I go awhile without replacing it, I get used to the decreased brightness, but it's always a bit depressing. Replace it and, boom! ... energy and excitement!
(er, that and Oregon Chai and Astral Projection and cleaning my office)
But it's mainly the lights! I had two of my three out... Replaced one. Back to two-thirds brightness. I need more. Stores are closed. I need fake plants and art too.
