Your schooling does't have to stop once you leave the classroom. As writer's, part of our job is to keep growing and perfecting our technique and one way to do that is by going to workshops and classes even after graduation. The Writer's Digest University is one place you should check out. Not only do they offer workshop on technique but they also have workshops where you can hear from the experts or have access to agents and editors in the field. In fact, they have an Agent One-on-One Workshop coming up where agents will work with you on the first ten pages of you book. Talk about a great way to access the type of industry people that can seem elusive. And that's just one of many and many workshops they offer.
