Back in October my book club decided we were going to make lifestyle boards. The first quadrant (top right) is career and ambition, the second is family and entertainment, the third is travel & leisure and the fourth quadrant is nostalgia.
Essentially you are selecting pictures that represent items in the categories (example: I might have a skyline of NYC but it might represent a large city or certain games - but it represents any board games, not necessarily one or two of them).
When we started out I thought the hardest quadrant would have been nostalgia, but I was wrong, the hardest part for me was my career & ambition. I really don't know what I want to do, sure I want to volunteer more, but what else? I struggled with this for months. The easiest quadrant for me was travel & leisure, and I still didn't have enough room.
This exercise was fun and really made me think. I recommend that you make one too.
