Be nice to your friends and family that help you move. It is a huge sacrifice of time and energy that will make your life so much easier. Moving 3 times in 3 years has taught us this lesson. Make sure you keep them fed and hydrated. Laugh a lot along the way and don't work them into the ground. (You might need them again someday.) But most important of all, make sure they know how much you appreciate their efforts... And when they need help moving, you can be their moving friend too.
