Music. Mostly heavy metal of various sorts. Everything from 80's glam metal - Motley Crue, Poison, Whitesnake, Ratt, etc. to thrash metal - Testament, Slayer, Exodus, Megadeth, Overkill, etc., to other heavy shit like Fleshgod Apocalypse, Emperor, Dimmu Borgir, Septic Flesh, Iced Earth, Blind Guardian, Sepultura, Stratovarious, Kamelot, etc., etc.<p>Mix in a little bit of Eminem, Dr. Dre, Snoop Dogg, etc. for a change of pace, and just jam out. That's one of my key strategies.<p>The other is to draw a hot bath, and just lay in the tub soaking and reading a book for a nice long time.
