Business thinkers' principles, explained

Each page explains the methods one business thinker has described in public, in our own words, with the letters, essays and talks they come from. Each one ends with a free AI skill that runs those principles against your own plan, numbers or decision, and lists the source for every principle it uses.

The skills review your work against cited principles; none of them imitates the person or speaks for them. The people named here are not affiliated with AI Skill Pod and have not endorsed it. All skills: the skill library.
