As for discarding it. Do as you wish of course, but I NEVER discard any story. I might not work on them for years, but sometimes I go back to them. My longest situation was a novel started in 1998 and finally finished in 2021.
Tend to agree. In my "back portfolio" there are any number of half-finished things waiting for... well, you name it... ideas, amendments of various kinds... but mainly inspiration.
Discarding may lead to quite sincere regret!
