You already gave the answer yourself. You need to reflect on the topic beforehand. Something that is truly brand-new, you probably got some notification ahead of time that would have allowed you to do thinking prep. Things that are much more relevant to what you're working on or your business might be much more ad-hoc, so then that means you need to be always trying to think deeply about the work that you do and understand and evaluating all the potentials that are available.
