Beginning writers can usually benefit greatly by joining a local writer’s group. You may eventually outgrow it and move on, but it’s a great way to make friends, find beta readers, and learn local outlets. LinkedIn offers a similar advantage when you’re starting out, but nothing beats personalized contact.
I don’t know what percentage of people out there are writers, but chances are you’re the only one on your block. Chatting, commiserating, learning, and interacting with other writers builds your confidence and can provide tidbits of information you won’t find anywhere else.
