I can’t (due to other priorities) give consistent time to a project unless it is very important. That lack of consistency means I have to spend time re-learning what I was thinking and doing which is both inefficient and not fun. Since the projects are either experimental or not that important, I’m generally more motivated to do something else.

Over time I’ve learned to not even start such projects, but LLMs have made it easier to complete such projects by making the work faster reducing the time variable in time over importance and easing the refamiliarization problem, adding to the set of such projects I’m willing to tackle.

lack of character, distracted by other things for to long, drowning in unforeseen complexity, much slower progression than expected, bored with it, force majeure, etc
