Finding a writers group is not that hard. Especially down here in the Sarasota area. In fact I belong to four. Finding the right one for you is sometimes more difficult.
In 2012 I met with a small group of writes and we founded ABCBook4Children&Adults, Inc. We started out exchanging information on everything to do with becoming an author, from finding a publisher to marketing after. We had all made expensive mistakes. We paid much too much to get our books published. Our group was not interested in agents, query letters and finding a Traditional publisher. I didn't write my first children's book until I was in my sixties. I couldn't wait around for what might be years to see my book in print. A lot of writers feel the same way. Along came self-publishing. It's come a long way from the old vanity press day. I read some of those and they were terrible. They contained stilted dialogue, punctution and grammatical errors.
Does it still happen today? Yes, and even in the Traditionally published books.
What has changed is the quality of the work being published by self-published writers. They know that to be taken seriously they have to produce the best product they can.
That said what type of writer's group do you want to join. Do you want a critique group. A group that will help you refine your work. They will meet in libraries and coffee shops.
There are some like the Sarasota Authors Connection, that have great speakers come and you listen and hopefully take home some words of wisdom to use in your writing.
The Florida fictions Writers group has conferences and workshops. They have agents come to these and you can pitch your work and hopefully get and agent to help you get traditionally published.
Then comes the writers group I'm most proud, of the ABC Group. We try to help with the marketing of your book. No one will buy your book if they don't know it's out there. You have to use every trick in the book to let readers know about your book. social media, go to events, set up book signings. We attend at least ten events or more as a group.
All the writers groups are great to belong to. Authors are willing to share what they know. If you are serious about being an authors try to find one in your area. You will make friends, talk books, exchange information and have fun.
