Also, not killing bugs. I prefer to safely escort them outside so they can live to see another day!
Books: The Sun Also Rises, For Whom The Bell Tolls, The Rum Diaries, Fear and Loathing in Las Vegas, Into the Wild, The Great Gatsby, Jupiters Travels, Riding High, On The Road and many others.
Music: This sounds cliche I'm sure, but I like just about everything. If someone put their time and energy into it, something good can always be said about it.
Food - Definitely anything.
