A good way to get an idea of what you may need for yourself is to ask yourself..."Hmmm....What do I use to get me through the day?" (It's amazing what we don't even pay attention to using because its so routine it goes without notice).
Things such as, bathroom accessories, (towels, cloths, mats, etc.). Same for kitchen uses...(can opener, dishes..blah blah, etc.).
I'm preparing for another move....after residing here for 13 years! Since the beginning of the preparation for the move, I have been absolutely amazed of how much stuff I've accumulated over the years.

What was I thinking?? (I have far too many hobbies....lol).
The first move is always the most exciting. Good luck, and enjoy.
