(Thanks to @ChrisK for the query!)
  1. Read a lot
  2. Ponder
  3. Perseverate
  4. Procrastinate
  5. Poll my producers
  6. (Sometimes) Just ask the person what they want to talk about
  7. (Always) Be willing to drop my plans if the interviewee says something surprising on the air, so that I can pursue this new/unforeseen avenue
  8. Hope for the best
