So I've been thinking about your question/conundrum for a couple of days, and I have an idea:
One of the things you need to do for a Will, is to define all your "items of value". So basically anything you own that is worth more than $1000, or any collection of similar things that are worth more than $1000.
So while your car is in the first category, your XBox isn't.
But, if you have an XBox 360, XBox One X, PlayStation, Nintento Switch, 700 games for various platforms, and custom controllers and sound system, your "Gaming Hardware" classification may be worth more than $1000.
So make a list of everything you own that is "valuable". Just do it in Excel. Easy peasy. Item Name, Description, Location, Approx Value.
Then add a column titled "Who gets it", and write the name of the individual, organization, or charity that you want the item to go to if you fall over dead tomorrow.
"Gaming Systems, All my gaming equipment and games, Living Room, $1100, Bob Smith"
You can do 90% of this while sitting on the couch, looking around the room, and thinking about the things in the other rooms.
Here's the fun part...
So while this is nominally needed for the Will, what you will find is that you have a lot of useless shit cluttering up your life, and you will want it GONE.
So pack up 4 boxes of generic shit that you don't want any more, drive down to Goodwill, and give it to them.
Go back home.
You now have more space.
Things are more orderly.
Your brain is happier because some of the shit it was having to juggle - ("... gotta remember where I put that extra toothpaste tube..." - has been taken care of, and freed it up to do more productive things.
And this will feel good.
And inspire you to further action.
And then you'll discover Marie Kondo and go totally insane. Or not. Your choice. :-)
But, either way, you have done two things: A bunch of home projects while stuck at home, and done some baseline organization that you can push forward into a basic Will, with about 2 google searches and a generic form you can find online and fill out.
Bam! Accomplishments up the wazoo!
