Principles are our summary of their public statements.

• The Idiot Proof Test

  Strategy

  Invest in or build businesses with models so simple and robust that even mediocre management cannot easily ruin them.

  Supporting quotes

  • “When somebody says, "Any idiot could run this joint," that's a plus as far as I'm concerned, because sooner or later any idiot probably is going to be running it.”

    “If you don't understand a company, if you can't explain it to a ten-year-old in 2 minutes or less, don't own it.”

    “Corporate profits will be a lot higher 10 years from now. They'll be a lot higher 20 years from now. That's what you can rely on.”

• The Two Minute Rule

  Learning

  A founder must be able to articulate their business model and value proposition simply enough for a child to understand quickly.
