30% off everything (Black Friday Sale)

Hey deep thinker —
Just dropping a small Black Friday ripple your way: all my ebooks are 30% off.

Each book = about the cost of a latte.
Except instead of caffeine, you get clarity. :)

• The Idea Mansion (note-making system)

• Thinking in Analogies

• Thinking with AI

Thanks for being here,
