I know that we live in a new, techie age, but I’m a big believer in a paper address book. It will save you a lot of frustration when your phone or computer crashes, or the screen gets broken, or you get a -gasp!- blue screen of death.
If you already have a paper address book, this is your reminder to update it. Message or call your friends and family to check if you have their current addresses and phone numbers and update.
If you don’t, I highly recommend you get one. You can buy a cute paper address book from the store, or print your own pages, I use this one –
Then, just fill them in and put them into a binder.
You’ll be so happy to have a back up the next time you need them!
