How do you answer 'How do you handle a heavy workload with many deadlines' in a job interview?

The best solution I have found for unlimited work tasks are ''To do:'' lists. On Fridays, I list the '''major''' things I have to do for the next week on ledger paper by days of the week. I know when I leave Friday that I have the most things covered for the next week. On Monday, as I accomplish one of the items from that day, I mark off that task and start the next one. My phone rings constantly; listing and marking off completed tasks is essential. This is sort of like an abbreviated version of the Stephen Covey 7 Habits of Highly Effective People training but not as structured. Plus, seeing things I have accomplished and marked off as done encourages me to keep going.
