Richelle E. Goodrich said this quote

I don't so much mind looking back on having lost the election, or having been denied a role in the play, or having had my novel repeatedly rejected, or having been turned down for a date, or recalling laughter at my expense when I attempted some silly challenge.  Those things simply prove that I lived life.  What I do mind, however, is looking back on the lost opportunities where imagined concerns kept me from even trying—lose or win.  I've learned that there is no regret in a brave attempt, only in cowering to fear.
