Varies, but a common favourite is:<p>Time: Nighttime, preferably after midnight.<p>Location: In bed, with my laptop propped on my knees and waist, and my head up against some pillows.<p>Temp: Thermostat set on about 65.<p>Light: Just the glow of the laptop screen, <i>maybe</i> a lamp sometimes.<p>Beverge: A pot of strong coffee on in the kitchen. Usually a Sumatra or Columbian of some sort.<p>Music: Queensryche, Motley Crue, Def Leppard, Savatage, Dokken, In Flames, Children of Bodom, Iron Maiden, Testament, Godsmack, Vains of Jenna, Emperor, Nocturnal Rites, Blind Guardian, Iced Earth, Crashdiet, Bon Jovi, Borknagar, Bonfire, KISS, Kix, Journey, Lacuna Coil, Lizzy Borden, AC/DC, Annihilator, Agnostic Front, Armored Saint, Alice Cooper, Cinderella, Twisted Sister, Morbid Angel, Deicide, Death, Van Halen, Voi Vod, Vader, Warlock, W.A.S.P., Whitesnake, Five Finger Death Punch, Exodus, Overkill, Sepultura, System of a Down, etc.<p>As an alternative:<p>Place: Barnes & Noble cafe or Starbucks or similar<p>Time: Saturday, from about noon, until ...<p>Temp: Whatever<p>Light: Whatever. I usually sit near the windows, and if there's a lot of sunlight glare on my screen, I roll down the blinds to nix that.<p>Beverage: a bottle of Fiji water and a venti sugarfree mocha w/ whole milk, sugar-free caramel flavour and no whip.<p>Music: Same as above<p>In either case, I may sometimes switch up the music for trance / electronic music of some sort, preferably with no lyrics, or classical music.<p>If I'm home in bed, I'll occasionally forgo the music and put a movie that I've already seen 100 times (The Matrix, The Social Network, Sneakers, Hackers, etc.) on the big monitor across from the foot of the bed, and turn the volume down fairly low. I basically ignore it, but when I need a break from looking at the screen, I can look up and focus on that for a minute or two.
