Never give up. Apparently that previous sentence was too short. In that case, also, surround yourself with people who love to read and write, listen to them, and attend workshops. There are some very good ones, although I cannot advertise them here; see my twitter account for links to good events; enter competitions, as this gives you a boost when you are recognised and helps you to continue when others begin to doubt that you will ever succeed. Remember that the author of Stoner never saw his book's success. This happened to Emily Dickinson. And Jane Eyre was a slow burner. This may happen to you. Write as a gift and don't expect anything back.
