It took me years to pluck up the courage to start posting my writing. Just wait till the readers start responding to your work with encouraging comments (especially if you post on here).
I have had such a lot of wonderful comments to my work and a lot of great suggestions too, on how to improve.
I can't praise this site enough. Because of the people here i had the courage to submit a story to the loves landscape anthology on Goodreads. I now have a story published.
Please consider posting your stories, i for one will look forward to reading them.
hope this helps and good luck.
