The current issue of Writer's Digest is worth reading. If you aren't a subscriber, try your local library for a copy, especially if you've been agonizing over whether to go the self-publishing route or not. In the March/April issue, the staff gives a succinct and (in my opinion) unbiased assessment of the pros and cons of this thorny issue. In the end, publisher and editorial director Jane Friedman sums it up this way: "Self-publishing can be easy, affordable and satisfying--but marketing, selling and promoting can be difficult."
In the same issue, you have Michael Crichton's top five writing lessons, some great writing exercises from Dr. Charles Johnson, some excellent rules for self-editing, and five easy tips for strengthening your scenes by James Scott Bell.
I don't read every article in every issue of Writer's Digest, but I suspect that this one is going to stay on my bedside table for quite some time. And, no, this was not a paid advertisement. (Don't I wish it were!)
