You can get too much focus or too little focus.
It’s not an easy balance.
For example, you can focus too much on things you can’t control. “What’s the situation in the US?”. Ok, other than the general culture, why is it important?
But, on the other hand, if you only read “How to be more successful at X,” you’ll have a view that is too narrow.
There are other implications, also. You can consider what appears in the media as the ultimate truth.
For example, you think you know what it’s like to live in the US just by seeing the news. While not a lie, the image might be far from complete.
