Don't take too long to think about it. Fifteen authors (poets included) who've influenced you and who will always stick with you. List the first fifteen you can recall in no more than fifteen minutes. Tag at least fifteen friends, including me, because I'm interested in seeing what authors my friends choose. (To do this, go to your Notes tab on your profile page, paste rules in a new note, cast your fifteen picks, and tag people in the note.)
