question 2 sheet 5.

"Answer to 1. Disliked story: Bought a cupboard full of yucky peanut butter. Preferred story: Cleverly purchased good peanut butter in bulk. Fixed reality: You bought a year's supply of a peanut butter you haven't tried, and it's either tasty or yucky; if yucky, pretending to like it and choking it down won't get your money back."

That reality isn't fixed. Tasty/yuckiness is in part determined by your attitude towards the peanut butter. Tastiness is not a one place property. More generally, you can make yourself like different things. Doesn't just familiarity make you like things? There's a large grey area between tasty and yucky that includes a section for "has the potential to be tasty if I decide to damn well like it."

Sometimes, yes, you can make something not be wasted. The point is to reason from the situation as it is, not to avoid making sunk costs not a waste. As things go food is pretty easy to choose to enjoy, or at least not mind.
