I am amazed how much I did not know about what my wifes schedule looked like.  What was even more amazing was how many other couples run into this same issue and have no idea.  When planning out our life, for the few of us who do this on a regular basis, we are usually the one who chooses what tasks are important and what tasks have to happen today or can wait until tomorrow.  When you have a partner you are working with (Personally or Business) taking 15 minutes and reviewing both of your plans once a week will help keep the relationship strong and actually enjoyable.
