I have some stuff that is worthless...

To answer the question: no.
I have some stuff I'd hold on to as long as I don't need the money, like my nakayama and other hones. But I'd sell them as soon as I needed the money badly.

It may seem weird but I am not attached to my earthly possessions. They're just stuff. The only things I'd consider important are my wife and kids. All the rest can burn down with the house. Sure I'd regret losing some stuff, but in the end it's just stuff. I take good care of my tools and treat them with respect, but there is no emotional anchor attached to them.

This is something I learned from my mother and grandmother. My grandmother and father were beyond 'well to do' before WW2. She couldn't accept that they were eating real food while next door neighbors ate grass (literally). After WW2, most of what they had was gone because my grandmother shared / sold off whatever they had to help people survive. There's many a family in my home village alive today because of what she did.

So my mother, and afterward me and my siblings, grew up with the philosophy that stuff is just stuff. Care for it and respect it, but it's still just stuff.
