Really hate it when a project is switching focus every month or so. You start focusing and committing a lot of time to make things work. Taking initiative to enhance things. Then some weeks later management is switching focus and you have to port all fixes in the new code base. Then some weeks later you have to work on the things you did before but with some adjustments that result in the old code not being possible to use and you have to port fixes again. When complaining you sometimes get the question "how hard can it be, it's just some code". Some motivation is lost every time. And repeat this like a "while true" loop.
