I am sure that there are writers out there who can write in a vacuum. They don't need a how-to book or a critique group. They don't need support or encouragement or inspiration. And they certainly don't need to be spending their money on anything that might give them a leg up in the publishing industry.
I'm not one of them.
If you're not one of them either, I suggest subscribing to a writing magazine or newsletter. You can get one that specializes in your area of writing or a generic one.
I personally love Writer's Digest. Eight times a year I get a little dose of writing inspiration—personal stories of successful writers, how-tos, industry info and more. I don't just read the magazine, I actually try out their tips. If you don't have the $$ for a subscription, go browse their site. They've got all sorts of freebies there, from articles, to tips and writing prompts, to links to other great sites and blogs.
I also used to subscribe to The Writer (although when I had to make a choice due to my budget, I dropped this one and kept Writer's Digest). This mag also has tips and pointers and it comes monthly. The website has lots of free info, as well.
There's another one I just heard about called Writer's Journal. I haven't actually read this one but it looks like it may have some good information. (Anyone out there subscribe? Let us know what you think in the comments.)
So, what's the writing tip? If you need some regular inspiration and tips to keep you writing, subscribe to a good writing magazine and/or visit a writing website on a regular basis.
Are there other good magazines or newsletters you'd recommend? Let us know in the comments section.
