An example of my realism not being pessimism.
I have booked flights for the summer holidays because I hope to spend the summer in my other homeland.
However I have paid over the odds and picked direct flights from a British company rather than the 2 leg journey I usually make with a Middle Eastern airline because if one leg of the journey was disallowed due to Covid rules I'd lose money and the flights.
I'm sensibly optimistic whilst being cautious in case.
I certainly don't revel in disaster or lockdowns. It will be two years since I've been able to visit because we couldn't fly there last year. I miss friends and swimming in the sea and I have a shit load of business to take care of to keep hold of property.
True optimism involves being able to accept and roll with some restrictions and hard work now with optimism that we can cope with it and it will be worth it and the world won't fucking end if we have to suck up some difficult truths and there consequences.
That's mature optimism if you like. It's like the positive thinking business-the immature magical thinker stands in their window chanting the grass is short the grass is short and expecting it to magically get mown. Mature positive thinking would be more like right yes it's a total ball ache of a task but I can summon the energy to get the mower out and crack on to get it back in shape.
A bit of deferred gratification and hard graft to get to the other side.
