Firstly, I turn the whole situation over to God (Concept I).
I then have a little Conference with God (Concept II), and we exhaustively list all tasks I can and should perform immediately and in the short, medium, and long term to address the situation. Each should be broken down into its constituent parts, so I can have a plan for each one. They are then sorted into dates of performance and into an order.
I then turn the list of tasks (and sub-tasks) over to God, and ask God to retain ultimate authority over them (Concept I).
I then ask God to delegate back down to me the batch of tasks for the day, which it is my responsibility to take care of (Concept III).
Since everything is written down and being taken care of, I can legitimately set aside any temptation to dwell on the problem, situation, circumstance, drama, or crisis and deliberately turn my thoughts to God when tempted: God has this covered (Tradition X).
Periodically I report back in with God (Concept II) and we reassess the tasks. How often depends on how quickly things are changing: this might be monthly, weekly, or daily.
I find this method works well.
