"We Are All Accumulating Mountains of Things - and then throw it away"
Speak for yourself
It's an ongoing battle. I have no collections. The things I keep have utility value. What's too much? Arguably anything you have that you will never use is polluting your life but it's hard to know if something will be useful to you a lot of the time.
I used to bring things home I found, did this a lot, still do a little, but nowhere near what I did, partly because I have some money now. When you have no money and you have utility needs, you feed that... that's my experience.
I'm really good at fixing things and if I can fix something rather than toss it and buy a replacement, that's normally what I do.
My car is a 1997 and it's going strong. I'm typing on a used computer I bought online around 8 years ago. Most of my computer stuff is very legacy... I say so what if it seems to be fulfilling my needs. So many people here think I should upgrade. I will when I need to, such as when ATSC 3.0 comes online.
I have really gotten my money's worth out of the pair of pants I'm wearing right now! Does it look it? Looks OK to me!
I really should throw a lot of my stuff away, get rid of it somehow. It's something I think about, because if done right it will be very beneficial to me.
There's a lot of things I could use but I don't buy because I haven't researched them sufficiently to have confidence I won't be dissatisfied after buying them. I hate buyer's regret. I've made those mistakes but work really hard to avoid them.
