"Can I spend some amount of money and be done?"
"Is this worth spending some amount of money to be done?"
I have had innumerable projects where they just languished and languished and languished ... until I got annoyed enough to spend some money and then they were done and gone.
Sure, some projects are a "hobby". My hobbies are continuous and I like doing them so spending money to finish them is not relevant.
However, quite often a task languishing is either because I don't really like the task or don't feel like putting in the effort to learn the required knowledge. For those tasks, spending money often works.
(For example, my latest task along these lines was "sharpen my kitchen knives". After farting with far too many whetstones, I finally spent the money to buy a fixed-angle sharpening system. I took it out of the box, set it up, and in two evenings my dozen kitchen knives were sharp and pleasant to use again. I then put the system back in the box and put it in my closet for the next time I need it. I spent way less on that fixed-angle system than I have on the whetstones I tried up to this point.)
