Yes! I have a completely unfounded theory that sounds right to my gut that basically all that matters is time and focus. If you want to learn something all you need is time and focus, you can't get there with just one of those two, you need both.

The night before an exam, I can focus really hard and get a bunch of info crammed into my head, but it's all gone a week later. I haven't tried Blinkist but I struggle to imagine how it's any different.

A long books beauty is the path one takes to get to the conclusion the auther arrived at (over a much larger period of time themselves!), the debate, the details, the story, that's where the real "lessons" are. You can't just rip a page out of here and there, read them and call it a day. I mean you can, you just need to be honest with yourself in terms of what you're really doing.

There are no shortcuts to learning, you are always trading something away.
