START PACKING EARLY
If you know you'll be moving, start packing things daily. Pack a box a day, it will keep the doctor away! You'll feel less stressed, and won't be overwhelmed two days before move day that you haven't done it all. Pack the things that are easy to pack, like books, cd's, linens, and things you don't use on a daily basis. And remember, don't panic, every professional moving company can pack up what you didn't finish.
LET THE PROFESSIONAL MOVERS PACK THE BREAKABLES
You probably don't know this, but when professional movers pack breakables they're insured for their work, you're not. If any damage occurs that the movers did and they packed the box, it's insured.
IF YOU CAN AFFORD IT, GET THE MOVERS TO UNPACK
Get the movers to unpack your breakables, place them in the closet and get rid of the debris. And if you really can afford it, get them to unpack everything and put your things in place. It will save you days of work that no doubt you can spend in more pleasurable ways.
