I'm a writer of fluff, kibitzer, and especially interested in canon AU: Equestria Girls, the comics, etc. They are fun to play with.
"For fun" is the best reason to do anything. "The best" is the best way to do everything.
I hope that when the world comes to an end, I can breathe a sigh of relief, because there will be so much to look forward to.
It is a good and noble thing to tell a good story.
