First of all, decluttering helps a lot. We all store things that we haven't touched in years. I found it best to start doing a little at a time in anticipation of an impending move. Get rid of heavy items like books that one can donate to your library. Take only your necessary paperwork as it takes time to go through. Pack all of the small items in small boxes that are easily transportable. Pack clothes that you haven't used in a while or donate to Goodwill, as your probably not going to wear them.
As far as the bigger pieces such as furniture and such, help is required. It's good to be young but that is not an option for some of us. Round of younger members in the family, (the more the merrier). If your going to donate your furniture, they will pick it up for you. Again, decluttering of the contents in the furniture is helpful
I think the biggest thing is to keep reminding oneself it's all worth it.
