Pick your most frequently used content source.
Now, commit to not using it for one day.
Find an alternative source or viewpoint for today.
Ask your friends and colleagues for recommendations of a replacement.
Once the day is over, make any observations as to what you found different in your notebook.
We get into habits very easily – and rely on the same sources day in and day out. Forcing yourself not only to use another source, but also having to find an alternative, means that you are actively looking for other ways to ask and answer questions.
