Mental tasking is a more demanding area especially for Dominants who are creating such tasks for their submissives.  Mental tasking usually negated the need for physical activity and is used to exercise the submissives imagination or to spur creativity.  With that in mind, creating a a mental task can be as challenging for the Dominant to produce as it is for the submissive to perform.

I created this mental task to help my submissive focus on her ability to communicate to me her fantasies and desire.  This mental task is more of a meditation than anything else, but I have added on a component or reporting and writing.

I would suggest that you require your submissive to have writing implements such as a pad and pencil or a laptop handy so they can complete the reporting component of the task immediately.  

The instructions are relatively simple.

• You will set aside 20 minutes during your day to spend thinking about your desires, fantasies, needs, and wants.  
• You should arrange a place that is quiet and free from interruptions. A comfortable chair or couch is recommended.  The lights should be dim and the location where you will not be disturbed. 
• Get comfortable, close your eyes and think about your fantasies, desires, wants, and needs.  As you think about these things begin to prioritize them.  Your thinking should include details for the top 5 in your list.  You will have no fewer than 5 detail items about each of these topics on your list. 
• At the end of your 20 minutes, immediately jot down the top 5 main topics and the 5 details about each that you want to communicate to me when we talk.

When you have completed the task, message me immediately with the message "All done Sir."

At your next contact, or when convenient, discuss these topics with your submissive. Be prepared to ask follow up questions.  This discussion should give you a much better insight into what your submissive finds arousing, what might be missing from your relationship, or what she thinks is the important aspects to your relationship.  This can be as much for your benefit as a Dominant as it is a task for your submissive.
