The simplest way to learn is to read.

Not only do you learn new stuff, but you get better at reading (which makes it easier to learn new stuff).

Most usefully, reading fires off neurons in your brain, creating unexpected connections and insights.

Reading makes you creative.

Creativity is best way to find a game no one is playing.

Non-fiction, fiction, history, future, philosophy, religion, fantasy, it doesn’t matter what you read.

Just keep reading.
