We just moved recently and eventhough the company paid to move us i would recommend many tips others have mentioned.
1. Have a yard sale
2. Declutter as if you are having your house ready to show. Meaning pack early and get it out of the way.
3. Do not bring more stuff into the house than what is leaving. Ex. If you buy 5 bags of stuff at target 5 bags of old stuff needs to go out.
4. Start finding home for your plants. Amazing how much space they can take.
