"Way too many directions at once" just seems to be the way my brain works, so like Dennis above I've kind of learned to live with it. Some projects languish for a long time or don't pan out at all, but as far as I can tell nothing bad happens as a result---if someday I want to go back to Pintoid cameras and monobath development for a while, well, they're there to go back to, and if not, so what?

Obviously that's the perspective of someone for whom photography is strictly a hobby, though. I don't think that mode of operation would be too compatible with an actual artistic career.
