A) From Belinda Pollard, Australian book editor, consultant & owner of Small Blue Dog Publishing:
What to do when you’ve finished the First Draft
Though her tips are meant for upcoming writers/authors who wish to publish their first book,
they are also applicable to newbie writers in fanfiction *solemn nod*)
What Makes a Good Beta Reader
You probably have encountered word ‘beta-reader’ in Fanfiction dot net, This blogpost helps you identify the role of a beta-reader in your fanfic writing adventure
B) Follow and/or subscribe to the following websites to receive regular #WritingTips

Daily Writing Tips
C) Just write.
Write your fanfic. I’ve read somewhere (i wish i could remember where)…
Write like no one else is reading it. Write like it’s only for one person in your life. Write it like you’re the only one reading it.
Go get a copy editor, proofreader, developmental editor, a beta reader. Go attend a writing workshop online or in your local area. Attend writing festivals.
But seriously, don’t write for fame or for reviews. Write for passion, from the heart, from your soul.
When you write what you love, nothing else matters.
And finally, remember to have fun. Make writing an enjoyable & positive experience.
