Here are some helpful hints to make the transition easier.
Start by doing everything you can't delegate. This includes deciding where you want to live and what you want / must keep. When you have made all the decisions no one else can make, progress onto the rest.
Do a floor plan. If you skip this step or say 'I'll just make it fit.' you are headed for disaster.
Use the good stuff. Don't save good towels, linens, clothes for tomorrow. Get rid of the rags!
Change of address should be done 2 weeks before the move.
Change of telephone - allow 1-2 weeks, depending on the carrier.
Allow enough time / energy. Moving is physically and emotionally exhausting.
