It is often said that writers must be introverts and that writing is a lonely occupation. Maybe for some it is, especially when members of their family sneer at their efforts – but there are plenty of extroverts who love to write. For them it is another means of communication.
If you find writing alone is less than satisfying I suggest you try to find a writing group, or start one. It can meet in a member’s house, you don’t need a hall, or in the local library. Each group is managed differently but most need a leader who has some idea of the format of each meeting.
Most informal groups meet to discuss the writing they are doing at the time and to read out loud. If this is overwhelming someone else can read your work or you can just participate by commenting on other contributions. Sometimes groups can organise events such as book launches or sales at fetes and fairs.
A more formal writing group usually has an experienced writer as a leader who will give advice and use the time for writing exercises with homework for those who wish to do it. Groups can be made up of writers of all genres or one. You might find a story-writing group or one that writes poetry or produces plays.
Local colleges sometimes have groups led by a professional writer and lecturer but these can be expensive. A flourishing group can help with book design, self publishing, marketing and promotion but often the greatest pleasure a writer gets from a group is just mixing with fellow writers.
Larger groups run competitions, invite speakers and are probably members of the National Association of Writers Groups (UK) NAWG has an annual conference which is well worth attending.
Writers can be sociable!
