Let's face it, not very many authors have the luxury of writing full-time for a living. Most have to squeeze their writing in around work, school, family and life in general. Time is at a premium so even though there are ton of books, magazines and blogs out there about how to market books, reading through them takes time and pulls an author away from doing what they love in the first place. So how can you learn the ins and outs of book marketing without sacrificing hours and hours of your time? Well believe it or not, YouTube actually has a lot more than funny cat videos. There's actually a ton of useful book marketing and promotion videos and most can be watched in under 10 minutes.

Chances are, you'll find something that will be both useful and entertaining. Who knew, right?
