*nod* That concerns me too and, as far as I can tell, I'm very much like Dan in many ways relevant to what I like to read and write about.
I suspect the difference is that Dan feels the pressure to keep a schedule while I'm much more willing to delay producing something in order to meet a certain standard. After all, everyone productive agrees that "perfection is no good if it means you never get it done" but where to draw the line is a fuzzy thing.
(For my story ideas, I'm taking the "plan out the whole novel/fanfic first, then fill it in like a progressive JPEG, then only share it with strangers after it's more or less done," approach... something that keeps getting me dopamine hits from a trickle of insights I never could have had from writing in linear order, which cause me to make significant but proportionately worthwhile changes to the character bio charts, backstory, etc.)
Heck, once I clear out some more urgent projects, I have a Scrivener competitor in a very early stage of development where the ability to pull up note cards which share a certain tag (eg. character bios) in a cross-comparison display is on the TODO list specifically because I'm finding it's starting to get laborious to double-check that my characters aren't evolving toward too much similarity as I continue to develop my conceptions of them.
