Just Gunk:

Have you ever went back and read what you written awhile ago and thought, "wow, that's good, it's as if I was someone else when I wrote that."

It's like you had to hold your breath for as long as you could and plunge into a deep black pond and reach the bottom and try to pull something up. And when you surfaced, you passed out and only days later could you tell if you pulled up something beautiful or just gunk.

Of course, most of the time, it is gunk.
