In the series of Writer’s workshops we did with Ardashir Vakil, we talked a lot about a writer’s Voice.
Here’s an interesting blog post on how to find your voice, and it recommends concrete exercises. I’m going to try them out and report back if I find that elusive entity.
Your thoughts on writing are true, and varied enough to hold interest. I'm very impressed by your ability to keep up this blog (as well as your others). It's something I aspire to do myself ;).
Please check out my blog sometime at http://chrysaliseditorial.com/blog/. I also offer mailing labels for literary magazines, if you're in the process of submitting any of your work. (http://chrysaliseditorial.com/blog/2010/01/address-labels-to-literary-magazines-available/)
Best of luck!
