Think carefully often about the priorities related to the work you do.
Then, keep the focus.
Ask clarifying questions when necessary.
Organize the schedule well so the focus is clear to the students you teach and colleagues you work with.
Make sure that most of your time everyday feeds the focus.
There's great temptations in schools to veer off the important course of serving children well, and in order to stay the course, we need to support one another in this regard.
