Productivity Tips

I'm curious as to how a lot of you in academia organize all the things on your to-do list, from juggling lectures, projects, even housework. Not looking for apps! I know one of the reasons why I struggle getting things done in other parts of my life, is because I always feel like I have to be "working." But this only ends up being counterproductive, as I burn out due to this mentality, and then nothing really gets done (or the quality is not good). For example, sometimes on Saturdays, I do mostly housework and light lecture prep in between. Saturday mornings are "finance mornings" so I pay all my bills from the past week.
