Obsessing over learning

I work in Security as an Architect and the imposter syndrome is real. I constantly obsess over what to learn as opposed to actually learning. There are so many areas out there, especially in a role like this that values breadth of knowledge. I have no idea how to approach it. Any tips for switching my brain off on the weekend and actually figuring out what to study?

MSc in CompSci and CISSP, so foundational knowledge is set.
