Generic bucket lists — skydiving, seeing the Northern Lights, visiting every continent — are fine as a starting point, but the ones that actually mean something are built from what the two of you specifically want, not a template.
A better way to build one: each answer these separately, then combine the lists.
Our Fantasy quizzes are a fun way to surface answers like this without it feeling like a planning meeting — take one together and see what you'd both actually want to add to the list.
