Although Ernest Hemingway NEVER said this, I wanna live by it. And I'm two shots in. I will not get drunk, but loose. I don't condone nor condemn drinking. In moderation it helps even perfectionists like me to ease out of being such a frissy-frossy. (See? It's working. I'm making sh*t up.)
There are studies suggesting one or two beers helps INSPIRE ideas, while coffee helps you FOCUS on these ideas. I'm in a chapter that needs to hurry up and finish so I can go back to action scenes, my easiest and more fun writing bits. Hence, the shots to help me unwind, and not fuss over how perfect the scene is. It's a complicated dialogue scene. Lots of information. Lots of stuff I need to just throw out there so when I go Revision mode, I can figure it out then. No biggie.
Don't worry about your first draft. It's rough because it's for YOU. It's to tell you the story, then you can revise and figure out how it tells others the story.
What does "Write Drunk" mean and how did the false quote become so popular?
You could take it literally or less than but the quote simplifies the writer's take on finishing the book first. When you go through the rough draft, you must keep writing, and not care about all the errors, and potential hiccups in your research. Your usual inhibitions are put away when drunk so try to put them away when you're writing.
What does "Edit Sober" mean?
Without mercy, revise, revise, revise. Remember how you tried correcting your mistakes when you realized what you did while you were drunk? Yeah. You're fixing those. The bad texts, the vocal regrets...you're editing those out of your story. But only Edit Sober when you're DONE WITH YOUR BOOK. Not when you're done with the chapter. Unless you're a blogger. Then yes...please...edit your blog post with murderous enthusiasm.
