Ever been on the verge of finishing a jigsaw puzzle only to discover the last piece has gone missing? And remember how frustrating it feels to not find it after hours of searching, only to discover it a day later hiding under the sofa's dust ruffle? A small but possibly life-changing piece of your own personal puzzle will fall into place, but only when you're not hunting for it. Don't try and force this; it'll happen quite nicely on its own.
