Moving might be the second most frustrating thing everyone has to do during their lifetime. I don't know what the first is but there has to be something more agonizing. What makes moving so painful is that it feels never ending, it's usually hot, it's strenuous and you are typically asking your friends to help you with something that you know they don't want to do.
I've been involved with many many volunteer moves and moves on my own. I should probably buy a truck and start a new company because over time I've learned a few Do's and Do Not's that help move things along and leave everyone thinking "that wasn't so bad".
Do start packing ahead of time. As you pack go through and decide which items you really must have and what you can discard, sell or give away.
