BJ Fogg's Behavior Grid. The Game Layer on top of the World. Game Mechanics. Get Mental Notes. Thank you to everyone who helped make Mental Notes a huge success. Of the original 5,000 decks, all (except for a small personal reserve) are gone. Don't fret! There's more in store: An expansion pack is in the works… There's a planned kickstarter campaign (where I'll offer up the remaining 1st run decks). Don't miss out! © Copyright Stephen P.
