I've been influenced by poets as diverse as Dylan Thomas, Lewis Carroll, and Edgar Allan Poe.
My reading is extremely eclectic. Lately I've been teaching myself computer graphics, so I'm reading a lot about that. I read books of trivia, of facts.
I'm working now on a collection of Shakespearean sonnets, about 100 of them, that I may publish if anyone's interested. My take on life is a little different from the bard's.
There's not too much difference between writing a picture book and writing a collection of a hundred poems or so, except that the bigger books take a lot longer to do.
Poetry seems to sink into us the way prose doesn't. I can still quote verses I learned when I was very young, but I have trouble remembering one line of a novel I just finished reading.
I keep a guitar around while writing and will improvise music. I do this for several reasons, such as that it's fun, and sometimes it helps me with the meter.
