Procrastination is a BS detector.
If that's true then all my school work and university assignments were BS.
But it actually does detect BS sometimes. Sometimes it even tells you that your mind is in conflict with itself. In the case of school work, maybe some part of you believes the material is useful to understand, but some other part of you is not convinced.
Sometimes that feeling can even nudge you toward harmonizing those parts of your mind. Which can be nice. (But not always truly necessarily.) For example, my CS degree required a digital circuit design (EE) class that I didn't enjoy at all.
But in hindsight, I am now absolutely convinced of its usefulness and relevance. If I could have been convinced of that while I was taking it, it might have been easier to do the work. Although I wouldn't assume that's a realistic approach because maybe I needed to learn it first and then apply it before I could appreciate why it's useful. Sometimes you need to just power through even though you're not feeling it.
Still, the point is that procrastination served as a kind of an indicator that I felt it was BS. It doesn't necessarily fix anything to know that, but it's not wrong either.
