english: So how could this be happening? I think part of the reason, a big part of the reason, is that when our minds wander, we often think about unpleasant things, and they are enormously less happy when they do that, our worries, our anxieties, our regrets, and yet even when people are thinking about something neutral, they're still considerably less happy than when they're not mind-wandering at all.
non_english: Ako je to možné? Myslím si, že čiastočne je to preto, že keď sa naša myseľ potuluje, často myslíme na nepríjemné veci a to nás robí oveľa menej šťastnými, než naše starosti, úzkosti, výčitky, a predsa aj keď myslíme na niečo neutrálne, sme oveľa menej šťastní ako keď nesnívame vôbec.
