This morning I listened to a panel of fiction writers at the Maranatha Conference. One of the questions they answered was “What resources have made the biggest difference in your writing?” Here is what some of them said:
The Internet is helpful for writing details on topics you are unfamiliar with, but after your first draft, you should have face-to-face encounters with people who have had experience with those topics so that your writing will be more authentic.
Learn to say no to other things that take up your time so that you have enough time to write (the example that Ann Byle provided was to give up cleaning your house, haha).
Get some critique partners.
Broaden your own personal experiences.
Be open to trying programs, such as Scrivener, that help you organize your writing.
