Good planning and organization is a key for successful move. "You should keep a special notebook with all the planning, tasks, and important move-related information."
Get rid of the items you dont want to move by having a garage sale. Allow yourself enough time to organize it. If you dont want to deal with garage sales consider donating your unwanted items.
Be present during the move. "It is important to be present at the location from the time the moving team arrives to the very last moment when the truck leaves your home. If you cannot be present during the move, or you have a problem to be home to greet the movers arrange for someone to do it for you. You might be facing extra charges for the time in case the team will arrive at your home before you do."
