Finance ✦ Penny’s Take
The Back of the Napkin
Dan Roam · 2013
83/100
👍 Worth It
Dan Roam does something unusual here: he makes a case that visual thinking is a learnable, structured skill rather than a talent, and then actually teaches it through a concrete codex. The vision-science backing gives the framework intellectual weight that most creativity books skip. If your world skews tech and corporate the examples will land cleanly; other readers may have to do a little translation work.
