A major problem I've seen with Engineers following a TODO-like tasks is that you get lost in the small things and lose focus of the bigger picture.
While they are useful, I also try not to forget things that are vastly outside of the list like regular user testing, talking about it with other fellow engineers (dev testing?), try to make a workable MVP and sell it early, etc.
Need an overarching vision. Absolutement. That's why I like to simply keep track of what I am doing or want to do in a calendar-like way. I never delete things from my logue of completed tasks, I just keep adding new dates and new ideas/finished tasks/want-to-dos at the top. It works well when you have an overarching goal.
