Between the time block in calendar, you have the transition period. This transition period can easily make people procrastinate. To help avoid wasting time because of this, you can count your next tasks (usually a group of subtle tasks) in this transition period using 1-2-3-4 method. To remember this more effectively, you can put out your siri, make a quick note, write down things you need to do next. Remember the list of items that you need to do.
