"The very first thing I tell my new students on the first day of a workshop is that good writing is about telling the truth."

And that's just what Anne Lamott does in this book. Telling some truths about writing.
Like this one:

"Writing can be a pretty desperate endeavor, because it is about some of our deepest needs: our need to be visible, to be heard, our need to make sense of our lives, to wake up and grow and belong."

Or this one:

"Writing is as easy and amusing as washing a cat."

And this one:

"Writing is about learning to pay attention and to communicate what is going on."
