Our knowledge of the world is like a jigsaw puzzle, making up of different pieces, big and small. Every piece can lead you to find another piece of the puzzle. Do not simply focus on find the pieces that seems big or important. Do not forgo any chance to get a piece of the puzzle regardless how small and insignificant the piece might seem. Putting that insignificant piece on your board might lead you to discover pieces that you pieces that you never thought existed or pieces that you have always been looking for. You might even learn that the pieces you have placed in the past were in the wrong positions.
