(a) big picture. Read about the past centuries, millennia. In a lifetime that only lasts an hour, appreciate how much, how little is within our power. Democracy is an outlier. Individual freedom is an outlier. But total dystopia is also an outlier (and not to be expected).
(b) appreciate that the balance of bad and good that we see is not a zero-sum-game, we aren't presented a ratio. We are presented with negative and positive narratives independently. Some of the negative narratives we see today are over-rated, and many of the lesser seen positive ones remain very valid.
(c) almost nothing is a tipping point. The systems of our world are full of feedback loops, and often extreme outcomes are averted by (super-)exponential costs that ultimately change our behavior. There are dynamics that humans can't run away from, and they will (probably) not be the spontaneous destruction of earth, but rather a gradual forced change of behavior.
