It sounds more like lack of discipline than bad organization. If the person you're working for (i.e. yourself) says that today you should do whatever sounds more fun to do that day, then it's no surprise that when this thing is not fun anymore, it will be paused and put back into the backlog, and velocity will suffer as a result. If you work strictly only on the fun stuff, that's something you'll have to accept. If you want velocity, you'll have to come to terms with doing unfun stuff from time to time. If you want only fun, you'll have to come to terms with sacrificing velocity in exchange for whatever short-term dopamine hit your brain wants to receive in this particular moment. If something stays fun for a long enough time to deliver, then that's either a nice coincidence, or you somehow found a way to force yourself to have fun even when you dislike something. Working for others (employer or customers) usually doesn't have this problem because then they would make it easier to prioritize tasks that need to be delivered to bring in some expected value (whether that value is the same as expected, is another thing). Something is wrong and should be fixed, or we need to do this because it's been requested a lot, etc. And the possibility of losing income (or something else, physical or not) tends to give a large boost in discipline.
