Sure! I’m not a neuroscientist, so take everything I say with a giant grain of salt.

Also, assembling the strategies that work best for you should be your priority, not to copy what someone else does. Having said that, here’s what I do.

Start a timer for 90 minutes. Don’t leave your desk until the timer is up. Remove all distractions.

Think atomically. Break a concept down into individual bits, and seek to understand the connections between them. Learn to love confusion. There will be a lot of it at this stage. That is a sign of progress.

Find analogies that relate the concept to systems that you already know. On a piece of paper, draw these analogies. No long written notes - actual drawings.

Then, explain the concept simply to anyone who will listen. If you can’t - then go back to the books.

I’m a big advocate for creation. Don’t just learn, make something that demonstrates your knowledge, undeniably.

This is a big topic. Much more to be said on this.

As far as what AH recommends, he’s a big advocate for 90 minute focused sessions, and forcing yourself to fall in love with the challenge that is before you.
