>I either wish to know or that I should know already. So let's back up. What's your motivation here? Why do you want to know stuff? Is it to excel at your job? Is it to just be a well rounded individual? Is it just because you love learning? Your goals should dictate your focus - figure out what you're trying to do and focus on that. There's only so much making time - optimize for maximizing it with a narrow focus on valuable subjects. If you want to make more money in your career, focus on things that will do that. If you want to be respected at your job, that's probably a different skillset you need to focus on. Understand what you're after; it's much easier to learn if you have a goal in mind, and it's much easier to set a goal when you know your motivations. Second, what is this about what you should know? In what context? According to whom? Is your knowledge deficient at work? Do you not know how to act around people you want to be romantic with? Are you making mistakes at work? What external force is determining what you should know? Is it imposter syndrome? I think getting to the bottom of your motivations and this feeling of not knowing enough or not knowing the right thing might be more beneficial than learning tactics for studying things. If you use good study techniques on the wrong thing, what's the point?
