I think this perfectly encapsulates why I take so long to finish things (besides the usual reasons)
Me, scrolling through my one-shots with the intention to work on one specific one:
*thinks about the newest scene of an entirely different one-shot*
*decides to grab my phone to read over that one^*
*tells myself to at least open up the one I'm gonna work on*
*sees a different draft and decides I'm gonna read over that too*
This process or something similar happens pretty often
