people bothered by cold hands imagine alternatives like warm hands. they have had warm hands. they know of summer and gloves and heaters.
if the laws of physics didn't allow for other temperatures, most people wouldn't be sad about their cold hands. they couldn't imagine any different, so they wouldn't see a problem.
suppose they were somehow bothered by cold hands that were IMPOSSIBLE to change. a rational person would then go "well i can't change my hand temperature, but i can change my attitude to it." they'd focus their problem solving on their interpretation so the cold feels neutral or good to them.
suppose i had an issue with cold hands in the real world. i don't wanna go to my car to go to work b/c my hands will be too cold. i don't own any gloves or hand warmers. ( http://www.amazon.com/HotHands-Hand-Warmers/dp/B00PX20LO0 )
i also don't want to miss work.
i had bad foresight.
what do i do?
i come up with a plan for how to proceed from here that sounds good to me. it will involve getting gloves (maybe 2 pairs to layer) and HotHands, and perhaps some other things (like a warmer jacket, or a car with a stronger heater, or a portable heater that can be used in a car).
if i really don't wanna have cold hands, i'll call in sick, get the solutions, and go to work tomorrow.
or maybe i'll decide i don't wanna miss work and i can deal with cold hands one more time, given that i'll make sure it doesn't happen again.
i won't want the impossible like that i had better foresight in the past. i'll focus on productive ways forward and come up with a plan that i have no criticisms of. my poor foresight in the past isn't a criticism of my plan since no plan can change it. the poor past foresight could be used to criticize plans that don't correct it. repeating that mistake would be bad. but plans which deal with stuff well going forward won't necessarily have any criticism of them.
