The best advice I ever got...

I remember asking my father, Why do we need four newspapers? He said to me, “Unless you read different points of view, your mind will eventually close, and you’ll become a prisoner to a certain point of view that you’ll never question.” There’s a tendency to operate in a comfort zone and to want to read what is familiar to them. But if you are just used to following one person or one newspaper, you will miss the big shifts.
