Take the time to curate Facebook Timeline
Annotate your life
If you haven't done so already, you can add where you've worked, lived, and went to school. If you specify years -- such as when you started a job -- those items will be added to Timeline's stream of life events, even if they took place before Facebook's founding in 2004.
You can also add other life events to the stream, such as when you broke your arm and whom you were with then, or when you spoke your first word or got a tattoo. By adding them to Facebook, you signal that those things really did happen.
