Not actually a real quote (image source)
Hayao Miyazaki is famous for directing such charming, positivity-filled films as My Neighbor Totoro and Kiki's Delivery Service. He is also known for being astonishingly pessimistic and curmudgeonly in his real life, to an extent you might not guess from watching his films. While they frequently touch on topics that would bring out the righteous anger in anybody - most notably war and polution - their general outlook on facing such problems is so hopeful that it's a bit of a shock to find out that the guy directing them actually wishes for the apocalypse to happen within his lifetime.
Only Porco Rosso, with its more cynical protagonist modeled after Miyazaki himself, and The Wind Rises, which actually had to tone down a lot of its content to minimize controversy according to the documentary The Kingdom of Dreams and Madness, really hint at Miyazaki's personality. Notably those two films are his most adult-targeted ones; he decidedly prefers not to rub his pessimism off on the younger generation. There's actually something of an "odd couple" dynamic between him and Mamoru Oshii, whose films lean much darker but whose personality is significantly more upbeat.
For your enjoyment and enlightenment, here are 10 of Miyazaki's darkest and crankiest words of wisdom.
On modern life: "Everything is so thin and shallow and fake."
On dreams: "Today, all of humanity's dreams are cursed somehow. Beautiful yet cursed dreams."

On the iPad: "It's disgusting. On trains, the number of those people doing that strange masturbation-like gesture is multiplying."
