How I can tell I've grown:

BEFORE
Someone: I don't like (character) because blah blah blah.
Me: *is super upset and hurt*

NOW
Someone: I don't like (character) because blah blah blah.
Me: *is super happy because I want to create complex characters that resonate differently with different people*

This is based off someone in my comments on FM telling me about why they don't like a certain character. Their insight was really awesome and I'm actually super happy about it XD
