Become a polymath

If you want to become a polymath, one of the best things you can do is to learn concepts from across disciplines, connect them and build a solid foundation for your thinking.

That's why I created Mind Expander. It allows you to learn about concepts and ideas you've probably never heard of, one quick flashcard at a time.

With this tool, you'll understand concepts from dozens of disciplines, without spending 100+ hours reading about each.

If you like reading about mental models, you'll love this.

Here's what you get if you buy the Premium version of Mind Expander:

Exclusive concepts I won't add to the free website version

Get even smarter with the best concepts I reserve only for the Premium version.

See all concepts in one list, with a neat flashcard view to make learning faster

You'll have access to a Google Slides file where every concept is in one easy list.

I'll send you an email when new concepts are added

So you won't miss anything.

Lifetime deal

With a one-time purchase, you'll see every new concept I'll ever add. And you lock the current price when you buy now.

In other words, your price stays the same, while the # of concepts keeps on increasing!
