. Your closest relatives's phone number. . When you go somewhere new don't rely on your GPS. Look at the map the old way. Look at the landmarks. Know how your orientation. . Your national number, your insurance number, one of your bank accounts . Have a picture of your vehicle documents and know the basics of your vehicle specs . When you meet someone new try to remember their name with a little memory trick. You make a mental connection between their name/face and something you will remember easily. For example: I meet Stephanie. In my head I tell myself : oh that's easy to remember that's like my wife's cousin that died of a horrible cancer. I always try to make the wildest connections so it sticks. The force of this method is to mindfully say : oh that's easy and then make the connection.
