"[T]he phrases 'negative well-being' and 'negative experiences' are unfortunate because if something is negative, it sounds as if there is a positive counterpart. Better names may be 'problematic moments in life' and 'problematic experiences', because unproblematic, which seems to be the opposite of problematic, does not imply positive."
