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.
Avoid stock expressions (like the plague, as William Safire used to say) and repetitions. Don't say that as a boy your grandmother used to read to you, unless at that stage of her life she really was a boy, in which case you have probably thrown away a better intro. If something is worth hearing or listening to, it's very probably worth reading. So, this above all: Find your own voice.
