“Whenever a thing is done for the first time, it releases a little demon.”
Quoted on the web sans source. Not in the complete Poems. A 2006 self-help book attributes it verbatim to Dave Sim (see below) sans source. A 2009 reprint of Poems: Second Series mentions it in the introduction sans source (thus probably taking it from the unsourced web quote). No earlier attributions found.
Compare to a quote sourced to Dave Sim: "Anything done for the first time unleashes a demon." (Cerebus #65, 1984)
