My first advice would be to read, read, read, which sounds interesting coming in a digital age, but it's so much easier to listen to a poem than it is to sit down and actually read it and to hear it in your head and that is something that every poet or aspiring poet needs to be able to do, I think to hear it in their head.

Sure, it's hard to get started; remember learning to use knife and fork? Dig in: you'll never reach bottom. It's not like it's the end of the world -- just the world as you think you know it.
