What this quote means

Logical validity does not ensure that something is true; it means it follows a structure that makes it coherent.

Under fun's new administration, writing fiction becomes a way to go deep inside yourself and illuminate precisely the stuff you don't want to see or let anyone else see, and this stuff usually turns out (paradoxically) to be precisely the stuff all writers and readers share and respond to, feel.

Bliss - a-second-by-second joy and gratitude at the gift of being alive, conscious - lies on the other side of crushing, crushing boredom. Pay close attention to the most tedious thing you can find (Tax Returns, Televised Golf) and, in waves, a boredom like you’ve never known will wash over you and just about kill you. Ride these out, and it’s like stepping from black and white into color. Like water after days in the desert. Instant bliss in every atom.
