We will be the cause of our own undoing. It cannot be otherwise. But I have changed the why from thing to thing to thing. Which thing today?

Sequentially in order of thinking it

Hate
Stupidity
Greed

Hate
Stupidity
Greed

What else could it possibly be asks me?

ARROGANCE

We know everything there is to know and what we think is always right and what others think who disagree are always wrong.

Nothing so arrogant as the arrogance of self-delusion self-importance.

Arrogance
Arrogance
Arrogance

Will do us in.
