Writing
I disagree with the "no radio" part. I almost always have a radio going as I write, and it's almost always on a talk radio station. I can listen and write at the same time.
In fact, I often listen to Old Time Radio as I write. The old radio programs such as "Gunsmoke," "Fibber McGee & Molly," "The Jack Benny Show," "Mystery Theatre," and a dozen others. I also have a TV in my office, and I can watch it as I write, as well. Though there's seldom anything on worth watching. But I do watch two or three shows a week while writing.
Try a radio or a TV. If it interferes with your writing, get rid of it. If it doesn't, then keep it and enjoy. Same with the internet. If it's a problem, get rid of it. If it isn't, keep it and enjoy. If you lack enough discipline to work with a radio or TV in your office, you probably don;t have the discipline to be a writer.
As for novel/romance. A novel is a novel, realistic or not. Subject matter may make a novel a "romance," but it's still a novel, which is nothing more than an extended work of fictional prose. I'd even go so far as to say that most of the best literary works fit into the category of "romance," rather than mainstream.
Two hours of writing each day is a Good Thing, and just about anyone can find this much time, though if you want weekends off, take them off. And I never have seen the sense of staring at a blank screen or sheet of paper for two hours. All this teaches is how to stare at a blank screen or sheet of paper for two hours. It can even make a wannabe writer go to any lengths to avoid the computer altogether. Barring the rare bout of writer's block, I don't actually know a successful writer who has had to spend two hours a day, day after day, staring at a blank screen, certainly not at the beginning of their career, though too many recommend it for others. No matter how much they whine and complain, just about every successful writer I've know couldn't wait to get to the computer/typewriter/notebook.
And I have much better, far more productive things to do with two hours than to use them staring at a blank screen.
"Opening a vein" to get the words right is fine, but writing should be an enjoyable, pleasurable process. If it isn't, many other things are. I greatly enjoy the writing process. If I didn't, I wouldn't write. The money is nice, and I've made a good bit, but there's a million ways to make money, so why not find one you enjoy? You need to enjoy writing, and, again, barring bouts of writer's block (which I still think is a myth) it strikes me as highly odd to spend hours doing anything you don't enjoy. I'm willing to endure a headache or a stff neck if a deadline looms, but if it doesn't I'm not going to sit at the computer until these maladies hit.
If you have to force yourself to write, if you actually find yourself staring at a blank screen for two hours a day, day after day, for heaven's sake, find somethinge else to do.
As for revising work, revise as you need to revise. Some writers need to revise almost endlessly, some need only moderate revisions, some need almost no revision at all. The same is true for individual works or fiction. Trust your judgement of the work, and never revise just because some book or person says you should. There's no law against getting it right the first time, and I've found the better my first drafts are, the better my final draft will be.
