You should ask yourself how much of the noise and chaos of the world do you let into your life? You have absolute control over this. You don’t have to listen to the news endlessly, but can always recede back into your own life and wellbeing.
In not suggesting head in the sand. Only that you need to put limits over the extent to which the noise and chaos of the world will undermine your peace of mind completely. Because it can if you let it.
