For the love of household moving
Those people who are used to moving around alot, often keep their stuff down to a bare minimum, so for them it's easy to move. However, those who have lived in a place for a long time, when they get into household moving for them it is very tough. People tend to start storing and hoarding alot of stuff and when the time comes to move, all that stuff needs to come out. Making a check list for all your stuff and how you want to go about packing up is a good idea. You should always make a checklist even if you have hired a company to do that.
