Does it get better?
Of course, man. Thirty minutes and you find yourself already understanding? That's great.

Go super read and dip the sections that you want to learn more about for another 30 minute session.

The more you do it, the higher your level of understanding will be.

The understanding only gets better from here, and even if you have to spend another 30 minutes with it, that's only 1 hour when usually it would take you how long? Most likely multiple hours.

Congratulations, brain. Keep it up.
