About this routine

Warren Buffett's morning routine often centers on making high stakes decisions by eliminating unnecessary clutter. At Berkshire Hathaway, Buffett and his partner Charlie Munger popularized the concept of keeping three virtual boxes on their desk: In, Out, and Too Hard. Rather than attempting to solve every complex problem, they immediately discard anything that falls into the Too Hard pile.

This 50 minute framework translates that mental filter into a step by step review session. You begin by mapping your circle of competence, setting explicit boundaries on what you truly understand. Next, you rapidly screen incoming opportunities or ideas, placing anything overly complicated or unpredictable straight into the Too Hard box.

For the few items that survive, you examine their structural strength and competitive advantage. The session concludes with a clear choice: either move forward with an obvious decision or reject it outright. By refusing to agonize over ambiguous choices, you protect your time and energy for rare, high-probability wins.

Why this routine works

  • Eliminates decision fatigue by discarding complex options early
  • Keeps choices firmly within your circle of competence
  • Prevents overanalyzing uncertain or unpredictable business pitches
  • Creates a fast, repeatable review process for big commitments
