I really like I should be Writing. It's not the most concise writing show (I'd recommend "Writing Excuses") and often the host wanders of with some tangents. It does cover a lot of the psychological aspects of writing and can be very motivating. I should be Writing frequently has interviews with famous genre authors which are worthwhile, if sometimes a bit long.

I just love Mur's podcast. I listen to many good ones, amongst them Paula B. and Writing Excuses but Mur's is the best. Always encouraging, always honest, always awesome, Barbara
