Why this works
Not every goal needs a metric. "10 Firsts for 2027" is a different kind of list — ten things you'll do for the very first time, from a solo day trip to asking someone you admire for advice. Once you do it, it's not a first anymore, so you cut it off the strip and it's gone for good — a first can only happen once.
That makes this list a natural fit for CutDone: numbered, Any Order, one cut per first. Print it, keep it visible, and let the list of firsts get shorter as your list of stories gets longer.
