Writing Excuses is a short podcast (tagline: “15 minutes long, because you’re in a hurry, and we’re not that smart!”) about writing fiction, with a focus on spec fiction (sci-fi and fantasy, though much of it applies to other kinds of fiction and other kinds of writing). The 3 hosts are Brandon Sanderson, Howard Taylor, and Dan Wells.
I started listening because it had Brandon on it, but the fun, brief episodes were so interesting and encouraging that I’ve continued. In fact partly because of the podcast, I’ve actually become a writer now. I’ve started working on my own fiction for the first time since childhood.
Recommended episodes to try:
Exposition (with Patrick Rothfuss)
Magic systems and their rules
Lessons from puppetry (with Mary Robinette Kowal)
