The most important thing you can do if you want to be a published author is to write. Lots. Imagine you wanted to be a concert pianist. What would you be doing every day? Practising! It's the same with writing. You don't see budding pianists sitting around all day in the music biography section of the library. They're at home doing the scales, day after day, making their fingers nimble and setting pathways in their brain of how to produce music. It's the same with writers. Attending writing workshops and reading how-to books helps to pick up theory and the inspiration to keep going, but its only in the practise of writing every day that you'll discover whether you're talented and if you can hone your craft of writing to publication standard. Reading has its place - you need to be passionate about the written word to be writing in the first place - and I certainly recommend reading widely to pick up the 'template' of good writing, but if you don't allocate a block of time to writing every day, your chance of becoming good enough to be published is slim.
Note: if you need help with grammar, do get that sorted before you do lots of practise. The best book on grammar I've read is "Elements of Style" by Strunk and White which is now available free online here.
So, I've just told you that you should be writing! But if you're still here reading :-) below are some of my writing tips that might help you with craft or inspiration.
BASIC - Advice on Premise, Characterisation, Conflict, Setting, Plot, Structural Edit, Line Edit and Formatting for Publishers)
ADVANCED - Notes from my Passion, Persistence and Potent Prose Workshop
GETTING PUBLISHED - Quotes from publishers and best-selling authors on how to get your book accepted for publication + the story of my own road to success
WORKING WITH LOUISE - If you're dedicated to your writing and would like professional help to improve it, I offer Manuscript Assessment (at certain times during the year), Mentoring, Workshops and Retreats. Click on the link for details.
And best of luck with your own writing journey!
