These days I think of the folly of fun, as "we want to have our cake, and eat it too" (illusion). But what we get is, "you can pay me now or you can pay me later" (reality). Being a parent, I'd like my daughter to grow up paying attention to reality. We'll see how much she's able to do. But I regularly point out the tradeoffs in life. Even though we may get focused on a particular desire, and be oblivious to everything else, the tradeoffs are always there.
