Some story games to get you going with your own story. Read - get loads of ideas about how poems and stories can work. Read - get lots of ideas about different styles of writing. Read - find out what you really like reading and have a go at writing that sort of thing yourself. Don't worry about being a copycat.
Most writers start by copying a style they like.
It's important to go back and redraft - the first go doesn't always work. Get something down and then make time for the second stage, to redraft. It can be disruptive to edit as you go along, so a word-processor is good to get all your ideas in one go and then go back and edit it. I like to see it on paper, so I print it out to read, and then redraft. The harder you work at it, the better you get.
