I have no doubt that we can create a really miraculous future. I am just increasingly pessimistic about our collective desire to do so.
So what if there’s a low collective will at the moment. Do your part to be part to grow the collective will to good. Go volunteer for a good cause (food bank, community organizations, etc.), donate to good causes, just be friendly to other people you see.
Pessimism that leads to a self fulfilling prophecy is irrational, but you still need a win. A win is fuel.
Choosing a belief that is less desirable than the most likely, is equally irrational, clearly pessimistic, and often self-fulfilling.
So the ideal belief system is irrational (optimistic) but only to a chosen and realistic extent.
Somewhere between Pollyanna and Eeyore, but more P than E. And as irrational psychologies go, moderate-P is by far the more successful of the two.
