How to start your move
Plan, plan, plan.
If you are fortunate enough to have some time before your big move, take the time to create a simple plan before you go and fill boxes.
Start digging from your closets and garage and throw out old stuff you don't need anymore.
This can be a complicated and frustrating process, and it doesn't really combine well with packing. So do this first, before anything else.
