I am one of those people who has to do something right when I am thinking about it. For example, I may think that I need to remind the teachers I work with that I will be in the library for a professional development session during their planning periods. Of course I think of these things a week before I actually need to do it so I use Boomerang. This is a Google app that allows you to schedule messages to be sent later. Here is a video to help you set it up if you think this is something you could use too.
