Tantek points to John’s post on Optimism Tax:
I’ll consider the loss to be part of my optimism tax. I sporadically pay this fee (when people take advantage of my trust in goodness) in exchange for optimistic freedom.
I would be less at-risk if I concentrated more on the negatives. “What if _____ happens?” But it’s not worth it. The cost to my quality of life (by worrying more) is far more expensive than the cost of losing some stuff.
I pay that, too.
