Crit partners, conferences, books, and yes...podcasts.
One of the best podcast out there for authors is Writing Excuses
Brandon Sanderson, Dan Wells, Mary Robinette Kowal, and Howard Tayler come together to make humorous and informative insights regarding the craft of writing.
And did I mention the podcasts are only fifteen minutes long? "Fifteen minutes long, because you're in a hurry, and we're not that smart," according to their website (but let's face it...they really know what they're talking about.)
Subjects range from genre, to voice, to time travel. There is nothing out there they won't tackle.
So try them out. I dare ya! www.writingexcuses.com.
Have a great week guys and good luck with the writing. ;)
