Gather all available information, assess the problem, you focus your attention, and you solve the puzzle.
People are a harder puzzle.
There's never one right answer and you never have all of the information.
Most puzzles come down to one last piece of information missing. Whether it's the answer to a mystery or to the question of who you are, where you fit, it all comes down to that last piece.
That's why the final piece of a jigsaw puzzle is so satisfying to place.
Unless of course, the piece doesn't quite fit.
That can make you wish you never opened the puzzle in the first place.
