I come up with ideas for short stories occasionally but I rarely sit down and try to write them, its hard to make time between the myriad of other things I'm interested in. This used to bother me, and the act of coming up with a story idea almost created a minute amount of stress when I didn't try to take it anywhere. I eventually came to accept it really doesn't matter if I follow through or not, if I accept early on what I really want to get out of it. The truth is the process of coming up with ideas and internally working through them is where I get most of the benefit, not in the process of having-done them. With this understanding, I realize I do get something out of the many ideas I have regardless of whether I follow them through, so I focus more on enjoying the internal problem solving/story exploring aspect and only try to follow through when I enjoy it, not to satisfy some need to accomplish things and be productive.
I'm not sure if thats a helpful concept to anyone else, but I've seen how other people get bogged down in unfinished projects, posts, stories etc and I saw myself going down that path as well. It ends up being very cathartic to physically box up a physical project, or delete a whole folder of bookmarks and just accept that whatever you absorbed was worth it and thats that.
