Try looking at things that surround you in a descriptive way. Don't worry about pretty, or the rules... don't ever worry about rhyming, but worry about rhythum -just let the words flow. Feel free to look at my stuff: http://myspace.com/crimsongarnet
(the new stuff that is) and read the comments I've gotten -maybe something there will strike something in you. Or simply, if there is someone you like everything about, or the way that person thinks... write it down.
That's all I have. Hope this helps....
