Please tell me:
* Who are you trying to persuade? Is it a child, a coworker, or someone else? Knowing who your target is will help me tailor the advice.
* What is the current problem with their usage? Are they spending too much time on it? Are they creating too many documents? Are they using it for purposes it's not meant for?
* What is your goal? Do you want them to use it less often, only for specific tasks, or use a different tool instead?
Once I have this information, I can offer more specific and effective advice on how to persuade them to use the creator document more temperately.
