“During the recording of her album Interiors, the musician Rosanne Cash posted a simple sign over the doorway of the studio.  ‘Abandon Thought, All ye Who Enter Here.’  Not because she wanted a bunch of unthinking idiots working with her, but because she wanted everyone involved—included herself—to go deeper than whatever was on the surface of their minds.  She wanted them to be present, connected to the music, and not lost in their heads.” ~ Ryan Holiday, Stillness is the Key (Page 43)
