I've had several jobs throughout my career that at times were very stressful. Sometimes, in fact, I would feel so much stress that I would almost become unable to focus on what to do next. Over the course of time, I've developed a few short guidelines on "How to Get through the Day", and when things get stressful and I can't seem to get a handle on sorting out conflicting priorities, I refer to this list. It works for me.
Begin with prayer
Spend time in the Word
Organize
Prioritize
Do difficult things first
Do one thing at a time and finish it
Pray, pray, pray
Treat others the way you want to be treated
Think about good things
Relax
