I realized that I get pleasure when I'm told, 'Don't listen to the haters; they're losers in their moms' basements.' I imagine these 'losers' and feel better about myself. Their insults hurt less if I label them 'pathetic.' I diminish their value in order to protect mine. I noticed that I'm quick to make a joke at someone else's expense.
I've learned that I've just barely scratched the surface of knowledge of the profession, and I have deep envy of and appreciation for filmmakers who really, truly understand the physics, the design of filmmaking. They can do story and color and composition and geometry and math and science all at once.
