A: Congratulations for achieving your goal.

B: Thanks! There were a lot of missteps along the way, but all of our plans have finally fallen in place.

Note: This phrase either means to “suddenly make sense” or “produce an ideal or desired outcome.” The saying may have originated from the game of the jigsaw puzzle. The game consists of a lot of small and irregularly cut pieces that are to be fitted together to form a picture. In the beginning, it’s more difficult because you haven’t got a clue where to begin with. It becomes easy as you continue playing. Nearing the end, some pieces fall into place naturally, and the whole picture becomes clear and coherent.
