Never sell anything that's broken.
Fix it up first, then re-decide whether you still want it.
Maybe you do and maybe you don't, but if you fix it first, you'll know for sure.
And you're right. You can't have anything nice. Neither can I. Sooner or later, BAM!
It's just the way it works.
I've met other people who CAN have nice things, but for whatever reason, some people can't.
My first car was wrecked, through no fault of my own (bizarrely), when I was 17, after I'd worked like a dog on it for months. Since then, I've never had a nice car.
I painted my Chevelle when I was 19. It looked good. I'm 62 now, still have the car, and I've never rubbed it out after that paint job.
Just can't (couldn't, before it rusted again) bring myself to do it. I know as soon as I make it really nice, something's going to happen to it.
Same for all my stuff. I drive beat-up stuff, live in a beat-up house, sit on beat-up furniture, and wear beat-up clothes. Almost every piece of clothing I have develops a grease stain within a week of getting it, so why try to have a set of "nice clothes"? If it's too nice someone's going to steal it, wreck it, key it, or otherwise mess it up.
It's not worth it. Better to enjoy crappy-looking stuff and relax, than worry about getting really nice stuff wrecked.
