"Note to Self" by Hans Hergot appeared in Daily Science Fiction on June 4, 2013. "A man has the opportunity to send a 6-word message to his past self."
I could not help but identify with the MC in this well-written story--a nice family man living paycheck to paycheck but otherwise happily married with children. I expected him to write something that would give his past self a chance at radically changing his future--lottery numbers, perhaps. What he winds up writing to his past self at first disappointed me, but then, on reflection, nearly blew me away. I love it when that happens. 6 out of 7 rocket-dragons.
