A Bottle Of Whiskey and a Notebook? Any advice for Writers?

“One day I will find the right words, and they will be simple.”

-Jack Kerouac, The Dharma Bums

I am working on my first book.  I write all the time in notebooks, but finally want to create a cohesive book/story.

I try to write every morning and always keep a journal with me in case ideas pop into my cabeza at random times (which they often do).

I read this bit on Hemingway this morning:

INTERVIEWER
Could you say something of this process? When do you work? Do you keep to a strict schedule?

HEMINGWAY
When I am working on a book or story I write every morning as soon after first light as possible. There is no one to disturb you and it is cool or cold and you come to your work and warm as you write. You read what you have written and, as you always stop when you know what is going to happen next, you go on from there. You write until you come to a place where you still have your juice and you know what will happen next and you stop and try to live through until the next day when you hit it again. You have started at six in the morning, say, and may go on until noon or be through before that. When you stop you are as empty, and at the same time never empty but filling, as when you have made love to someone you love. Nothing can hurt you, nothing can happen, nothing means anything until the next day when you do it again. It is the wait until the next day that is hard to get through.

On of my professors in college mentioned how Hemingway was a drunk.  So do I have to drink whiskey every morning to be an awesome writer like Kerouac?  Or be crazy like a lot of my other favorite writers?

Any writers out there have any words of wisdom for someone trying to write their first novel?  I have the luxury of time and not working a 9-5 so I appreciate any ideas of how to focus and actually FINISH a novel.
