One of the best ways to do this is to present a real-world example of someone on your team who does this well.

Walk everyone through an example week on their calendar and point out exactly how they are spending their time.

Then have everyone pull out their own calendar and have them go through the same process on their own calendar. Are they batching tasks? Which of the events are high leverage activities? Are there more efficient patterns to create? You should go through this process with your entire team at least once a quarter.
