Quote from : Duma Key Book

The truth has to come out, that's the basis of art. But that's not to say the world must see it. Be brave. Don't be afraid to draw the secret things. No one said art was always a zephyr; sometimes it's a hurricane. Even then you must not hesitate or change course. Because if you tell yourself the great lie of bad art - that you are in charge - your chance of the truth will be lost. The truth isn't always pretty.
