I think what to do is a more personal thing, from which one takes care of others and the world:-
Smile, be kind and have compassion, don't judge others unfairly, do what is good and right, say only good things of others, and don't remain silent or inactive in the face of true injustice or cruelty. Respect all life. This is the human challenge and journey.
To this I would also add in these difficult times… Understand that much of what we are told is opinion rather than fact. Our own formed opinions and views based on them should be considered potentially unreliable and should be questioned.
