I remember hearing about Writer's Digest wa-a-ay back in the olden days (must have been a high school English assignment). When I came across it online, I checked it out. This is where I got started looking for things online to help me out. They have classes, blogs, articles--all kinds of info. After I got a feel for what I wanted and needed, I started surfing the net for more. At least, Writer's Digest is a good jumping-off point.

Along the way, I bought more than a few books, but I can't recommend any of them. Writing is so personal, a book's author isn't likely to tell you exactly the thing you want to know. Sometimes the things you want to know aren't what you need to know. At least, that's what I found. And even more staggering--there may not be anyone who can tell you what you need to know. You have to get out there and find it for yourself.
Enjoy the journey! JP
