i have to walk away all the time. Some of the projects I have had For 5-20 years, I just dumped, because
I now realize I have neither the time or strength to restore.
Sadly, Ive seen some of these games change hands 2-3 times with no work getting done, as a bargain is a bargain, but like any other group, there are more pins that needs months of resto and sweat, then there is people with time to do.
Going through the garage again over the Holiday, to pile up parts, sell shit, and generally reduce again.
Only a couple easy projects to keep.
I hate to see the other treasures I have hunted down with much time and sweat to find, go for a price to move....but I am almost done.

Today, if its not a weekend or two resto, I have to pass...Ill never know if I can get the time to go further,
Makes me enjoy playing, testing new products, and some tinkering joy....more then enough.
It can get hard to see a garage, room or basement of projects, and walk by going, "ill get to those soon"

Better to just, "Walk away", as the Op says...

Now, why didnt I learn this about women years ago........
