Grrrrrrrrr mental block or rather too long winded.

I am trying to write a "story" for a client that I am working on to stop her from smoking. However, I keep getting "carried away" trying to put too much in and not wording it like I know it needs to be worded. I want to use her aversion to mess, such as she hates the idea that she will have dirty ashtrays around and she said when in the pre-talk that she only enjoys a few seconds of the cigarette as the rest of the time she is worried about getting the ash on her or other things, I also want to use her love of her 4 dogs as deterrents to smoke but each time I try to write something I end up with 4 pages. Do any of you out there love writing stories and would be willing to give me a hand or hell write one for me...yes I know a lazy way but I've been trying for 4 days now to get this out and am just finding myself going around in circles and the story getting longer and longer and me erasing and retyping and I am seeing her tomorrow. As you can tell I haven't used "stories" much in my limited practice. Mainly more "experiences" but I don't have any here coming from a non-smoking environment and all my friends are as well.
