Remember to enjoy yourself! It may not be super fun to have to move but if you stop and try to enjoy yourself then it will make the whole process go more smoothly.
It is best to pack your valuable possessions separate from other things. This way you will be able to keep track of them.
While this may seem like just another thing that’s added to your plate, get copies made of all of the keys before you move. In all of the chaos of the move it would be easy to misplace a key, and that is the last thing you want to deal with on your moving day.
