You do not know what the next shock from the world would be, you do not know what the next news would be, you do not know what the next wave would bring.
If you do not like this helpless state, then you will have to live as someone who is very surely unaffected.
It is possible, because the tendency to feel affected, is a choice.
It is a deliberate choice.
If it is a choice to feel affected by the world, surely the choice can be reversed.
Surely one can also choose to not remain affected by the world.
