Why do you write?
I write because I think. Writing helps me organize my thoughts, and remember details, feelings, and incidents that otherwise get lost (or transformed) in memory. I write for the same reason I read. It takes me to new places and new ways of thinking. I write for publication to give me more time to write, and to reach out to others I might never meet but through the written word.
Where do you get your ideas?
Every person, incident and place I see, hear about or read about has possibilities. There are always questions to explore. The big question is always “What if…”.
How do you become a writer?
Writing is mostly a state of mind. Everyone can find some time to put their butt in the chair. Then write. You have to train your brain to zone into writing at your will. It's not effortless.
How do you become a published writer?
Once you are a writer (see above), then hone your craft. Use books, classes, the Internet, writer's groups and conferences to learn how to write well. Publishing is a business, and you must invest in yourself as you would entering any other trade. Put your material out where you can receive professional criticism, like a writer's group or conference. Your mother can tell when you feel bad; your doctor can tell you why and what to do about it. Work with publishing and writing professionals for writing critique.
Finally, submit intelligently by researching markets. Read extensively. Know what and who is being published in your genre. Can you make an educated guess at the publisher from the subject and look of a book? You don't want to copy what is already in print, but you should be able to speak intelligently about your own field. Recommend a book to an editor as you would recommend a book to anyone; consider their interests, selection history, and what they say they are looking for. Don't waste your time, the editor's, or your fellow writer's time with inappropriate submissions.
Keep writing. Keep learning and sharing. Keep up with the trade. Keep submitting. Keep writing.
