Puzzles are great because they're fun. But really we are drawn to puzzles because they can be solved. We love the idea of being able to put a puzzle together and it being complete: you do it perfectly, step away, and you've completed the job. There's a deep satisfaction from that, and I think we wish for the ability to do that with everything. But emotions just don't work that way, people don't work that way, relationships don't work that way.
