How do you optimize your consumption habits and become a learning machine?

What do I mean by "learning machine"? I mean someone who's always acquiring knowledge, learning new things, and soaking everything up around them like a sponge. How do you become that?

Obviously, we all learn things every day, but how do you do that on hyperspeed? How do you acquire a ton of knowledge around you way faster than everyone else?

The key is to optimize your consumption.

To learn, you must consume. You must consume knowledge from other people and other sources. You’re consuming to learn, but you have to optimize that consumption.
