June 24: Create a contact list of your friends

At some point you’ll probably want to send someone something without them knowing. Vague? Yes. But what won’t be vague is you, completely out of the blue, asking your friend his or her address two weeks before their birthday. There are also circumstances you won’t foresee ­— wanting to send a card for a friend whose relative passed away, for example — when asking for an address won’t seem appropriate.

Instead, put together a database of all your friends’ contact information at their new residence. And while you’re at it put their phone number in it as well so you won’t have to create one of those annoying “I lost my phone, please give me your number!! LOL OMG!!!” Facebook events.
