I have been working on a side project that allows saving and sharing bookmarks with a simple like / dislike / comment system. It looks very simple, and is essentially a CRUD app. It's rewriting a similar project that had. That turned out to have taken over a hundred hours of my time, and still counting. I started in June, expecting to finish by August. It's November now and I'm still at only 80%. There are just too many details that can't be predicted before starting to work on the specific part. This happens at work too - "can you finish that feature now and release that in the next 15 mins or so"? Sorry, but I've only been a maintainer of this massive codebase for a few months, and haven't even touched that part of the program...? And yeah, I have other pressing work that I'm focusing on, so which one should wait?
