> More importantly, the process of adding to and maintaining the knowledge base felt more burdensome than beneficial
I wonder if being able to recollect things later in an organized way may not be worth the effort for you.
Something I've found is that I really don't need a robust personal knowledge base. My goal is to do my work well (and taking notes to support this is definitely valuable). Building a personal knowledge base doesn't support this goal and has a more unclear value-prop, so it's a drag to keep up with.
