I wrote a blog post back in March here:
http://sommerleigh.com/?p=355 about this subject. I started a writing group in my home town because I needed to work with other real writers. Except that no one who came to the group was a real writer. They all wanted to talk about writing, but few of them actually wrote and none of them spent the same amount of time and hard work on their WIP as I did. It was really disappointing.
I think there comes a time where a person who wants to write has to ask themselves, "Is this my job or my hobby?" If it's a hobby, then how and when you work on it doesn't matter. If it is a job, it has to be treated like a job where you sit down every day even if you just stare at a blank screen for two hours. I spend almost 40 hours a week most weeks working on my WIP. If I'm not writing, I'm researching. If I'm not researching, I'm editing. If I'm not editing I'm reading writing forums and catching up on industry news. I don't see many movies. I don't watch television. I don't spend half as much time with friends as I used to. (Also, I wouldn't give up what I'm doing for any amount of social life.)
I do it because I love doing it. Putting my writing first doesn't mean I'm sacrificing anything else. It's not a sacrifice when it's the first thing I wake up wanting to do. I make time for everything else, not the other way around.
Best piece of advice I've ever been given that I think should be handed out on a little business card to every person who wants to be a writer :
If you want to be a writer, you must write.Good luck. Changing your mind-set from being a mood driven writer to an every day, all the time, this is my second profession writer is tough. It requires completely changing your priorities. And unfortunately, there's no easy way to start than to just throw yourself off the edge and do it.
