Don't get it right, just get it written.
If I had a cent for every new writer I find who is overwhelmed by all the "rules" and "prescribed methods" to good writing, I'd be on my way to Tuscany by now.
The Internet is a wonderful place, and the blogosphere a treasure trove of knowledge and advice on writing. I love it. But I was lucky. I had too much of a confidence in my own abilities to be overwhelmed.
Why? Because I've written for about eight years before I decided to take the plunge and start a writing blog. So by the time I started nosing around the blogs, I already knew what worked for me and what didn't. I already knew where my writing needed help.
I knew that if I had conflicting pieces of advice, that I'd be able to pick the one that works best with me and the way that I write.
But note the words: FOR ME.
If everyone writes according to the way that works best for them, is there really a right way to write?
Short answer: No. The only way to write is your way.
Sure, you can take advice. If it works for you. You can deviate from the "rules", if you're willing to stand firm in the belief that you did the right thing.
Writing isn't about writing to a set form. If it was, every book would be the same. Who'd want that? Especially if it's a book you wouldn't like?
So, while it is excellent to see what options are out there (and I've seen some brilliant suggestions that I never would have thought about), don't sacrifice your own writer's identity in order to implement them.
Forget about being right. Get that story written, by any means possible.
What's your favorite writing "rule" or "best practice" to break?
