"Anyone can be a writer. All you have to do is write."
Every famous poet, author, journalist, screenwriter, etc. was once right where you are. Right where I am. While I do not profess to be an expert by any means, I wanted to compile a list of links and resources that I have found to be helpful on my own journey as a writer:
Character Worksheet,.doc and .pdf- There are a million different character bios out there, but this is the worksheet I usually use when I'm writing up a new character. It's my own mashup creation of several different bios I've come across. Great resource to help you develop strong characters. (.doc can be edited, .pdf is formatted for printing and filling out by hand)
Save the Cat! The Last Book on Screenwriting You'll Ever Need, by Blake Snyder - I prefer this book (the original) over Save the Cat! Writes a Novel: The Last Book On Novel Writing You'll Ever Need by Jessica Brody (although the latter is good, too).
Publisher's Marketplace,http://www.publishersmarketplace.com/ - This is THE place to go to learn about publishing deals, sales, and book reviews, and to find agents, editors, and overall news in the publishing industry. **NOTE: Always, always, always double check information on an agent, editor, or publisher by visiting their official site. Sometimes the profiles on PM are not up-to-date.
Predators & Editors, http://pred-ed.com/ - Good site to look up agents, editors, and publishers to verify credibility and read reviews from those that have worked with them.
For the indie author
Kindle Direct Publishing, https://kdp.amazon.com/ - Probably the most widely known and cost-effective self-publishing platform, which is owned and operated by Amazon. You can use your own ISBNs (see Bowker below) or use a free Amazon-assigned one (which can only ever be used to publish your book through KDP). Simple setup to publish both print and digital copies of your book (paperback only; hardcover not an option). Books published/printed through KDP are easily sold through Amazon.com and its affiliates and available as print-on-demand, so the author/publisher does not have to carry an inventory.
Ingram Spark, http://www.ingramspark.com/ - This is another independent printer, producing high quality books for the indie author (and many publishing houses). Print-on-demand services also available, but you must supply your own ISBNs, and every upload costs (for example, if you upload a new file to correct typos).
Nook Press, https://www.nookpress.com/ - This is Barnes & Noble's version of KDP/CreateSpace. You can publish your ebooks here to be available at BN.com as Nook books, and you can also publish print books. HOWEVER, they are not a print book distributor, only a printer, so you would have to have your books printed from them, then order huge quantities and distribute (or sell) them to bookstores, websites, customers, etc. yourself.
Smashwords, https://www.smashwords.com/ - Another great ebook publisher. You can publish your ebook into several different formats for distribution on several different sites: iBooks, Google Books, Kobo, etc.
Book Life, http://booklife.com/ - This is Publisher Weekly's site dedicated to the indie author. News, promotions, contests, and resources galore.
