Go through your list and put a star next to everything that is within your control and put a circle next to everything that is not in your control. You should only have between 7-10 items starred. Prioritize them in order of importance on a separate page. This begins a list of items for you to work on since they are in your control. Release the others as they are not within your control.
(When I did this, I had many more starred items than 10; so I went back and double starred 7 and prioritized them. I released the other starred items. I am making a matter of prayer the circled items; as I cannot control them, but I didn't want to release them either.
