Never walk away from failure. On the contrary, study it carefully and imaginatively for its hidden assets.
— Michael Korda

The truth isn't the truth until people believe you, and they can't believe you if they don't know what your saying, and they can't know what you've saying if they don't listen to you, and they won't listen to you if you're not interesting, and you won't be interesting until you say things imaginatively, originally, freshly.
— William Bernbach

Running a close second [as a writing lesson] was the realization that stopping a piece of work just because it's hard, either emotionally or imaginatively, is a bad idea. Sometimes you have to go on when you don't feel like it, and sometimes you're doing good work when it feels like all you're managing is to shovel shit from a sitting position.
— Stephen King
