- Pick off the easiest first
- Start with the one at the top and work down
- Look for the most urgent and start there
- Randomly plunge in and hope you can get them all done
- Delegate them and play golf (by far the best strategy, but during the round you'll think of twice as many items to replace them)
- Do the one that someone is shouting loudest at you to complete
The blue box, for 'Urgent and Important' things, is always going to get done first and needs to contain as few items as possible.
