This is my all time favorite quote about writing:
"You have a right to write it.Throw it out, rip it up, swallow it down.Build up a capacity to bear up--don't let fear ruin your writing life."
-Natalie Goldberg, Old Friend from Far Away
Perhaps I should turn it into a meme or something pretty, but I'm actually trying to write right now. I'm feeling stuck, so I looked up to this quote, which I printed in red and taped to my Wall of Notes and Inspiration.
