1. Do It Tomorrow-Free
This is the mother of all "to do lists." It has two pages of lists; one for today, and one for tomorrow. If you do not cross an item off "today" it automatically gets moved to "tomorrow." (You can also manually move items between days).
It's a great way to prioritize what needs to be done today and what can wait. Plus when you "check an item off" it makes a really satisfying sound.
2. Take a Break-Free
"Take a Break" was recommended to me by a masseuse, so you know it has to be good! When I can't sleep and am tossing and turning about assessments and meetings and all the business of teaching, I put on the "stress relief" meditation program. It may sound cheesy, but it really helps for those days/nights when you just can't turn off the running list in your mind.
There are nice options (as you can see above) to customize the program, too.
