Step 1: Be an enthused kid in love with a fandom. Create terrible cliche Mary Sue fanfiction.
Step 2: Grow older and realize how terrible you were. Recoil in horror and shame.
Step 3: Create only gritty and ironic deconstructions because real life is pain and you have been wisened to its ways.
Step 4: Slowly realize you still actually kind of like some of those ridiculous fantasies and old cliches. Remember how fun it was to boldly mess around.
Step 5: Cautiously approach older ideas. Realize that with some major adjustment, a couple of them are actually pretty decent. And even if they’re terrible, what’s so bad about being occasionally terrible?
