Use proper packing supplies - while it may be tempting to cut corners in the quality or integrity of some of your supplies, like using boxes that weren't designed for the purpose of moving, it will pay off for you in the long run. Imagine if the bottom dropped out of one of those boxes because you packed it with more weight than it was designed for - you may break some valuables that are worth much more than a proper box would have been. Another related tip is to put heavier items in smaller boxes to help maintain the integrity of the boxes and to make it easier to carry them.
It's also a good idea to take the knobs or feet off of furniture. This will help you get the items through doorways and tight spaces easier, and if you have all the feet in one place you'll make sure that you don't lose them.
And of course, plan ahead for the next few days after your move. Make a list of all the things and clothes you will need and put them in a separate box that will be more easily accessible for you. You might not have time to unpack all of your things right away, so it will be a big time-saver if the things you need for the first few days are all in one place.
From your local New Jersey movers, good luck!
