First: If you’re looking for another reader/editor, I am open to doing that for you. I give specific, detailed feedback (generally with examples from other authors), but I’m a bit light on the “tact” thing. I will try not to tear your work to shreds, but it’s really hard for me to soften honest criticism.
Second: “Get motivated for writing,” from what I’ve heard, is the wrong problem to have (which is annoying, because it’s a problem that I have as well). You need to be able to write regardless of whether you’re motivated or not. And it doesn’t matter if what you write when “not motivated” is crap; at least it moves the story forward, and if you want to come back to that segment and replace it when writing the second draft, you can.
Third: I find that nagging doesn’t help me at all; it gets me, as you said, irritated, and makes me want to push back rather than accomplish anything. I find stinging my pride works a lot better. “I bet you can’t write more this week than you did last week.” Or competition: “I bet that I can write more words than you can.”
Fourth, about quality: as the NaNoWriMo book, “No Plot, No Problem” says, when writing your first draft, you have to turn off your inner editor and just write. It’s often said that every author has a million bad words to write, and it’s best to get them out of the way as soon as possible. No book is good on the first draft. Your goal with the first draft is to write a book: not a good book, but just a book. After you write it, you can then assess whether the book can be saved through editing.
Fifth, about publishing: one of our hosts, Cory, has often said that the problem for writers is not getting paid when people read their work, but rather getting people to read it in the first place. Once you feel that your work has been competently edited, get it out there. For free, if that’s what you have to do to keep from getting screwed over. Once you have a bunch of people who want to read what you write, and something for them to read, then you can go about trying to monetize it. Until then, just work on getting words on the page, and getting eyes on those words.
Finally: If you’re really serious about writing as a career, then, from what I hear, it’s very difficult to get an agent without a published work in hand, and almost impossible (and borderline stupid) to go to a publisher without an agent. If you have any friends in any sort of media (newspaper, TV, books, movies, magazines, anything like that), then, once you have a few finished works ready for inspection, start asking around to see if any of their agents can get you an in with an agent who specializes in the kind of story you’re writing. The old saying is that it’s not what you know, it’s who you know, so be prepared to leverage who you know. Or, to put it just as honestly but less horribly: to give the people who want to help you the opportunity to help you.
I hope that some of this is a help to you.
Best of luck in your writing,
