Take the time to curate Facebook Timeline
Curating your life
You can change who has access to which posts. Like making an embarrassing photo only accessible by people who were there. You might want to delete other posts completely or hide them so that only you can see them.
You can change the date on a post. For example, if you had waited a week to tell the Facebook world that you broke up with someone, you can change the date to reflect that. You can also add where you were, retroactively using a location feature that Facebook now offers. For major events in your life, you can click on a star to feature them more prominently.
