Key takeaways
  1. Take ample time when making big life decisions. 
  2. Be suspicious of your intuitions. Vett your opinions.  
  3. Make sure you are answering the REAL question, not substituting with another. Identify when you substitute. 
  4. Ask yourself; do I really have all the information to answer this question? If not, what would it take to find it?
  5. Carefully curate non-leading questions in interviews and surveys, as anchoring, framing, and priming affect results. 
  6. Cut your losses, and adapt fast. Resist the sunk cost fallacy. 
  7. Happiness is a balance of long-term life satisfaction from the remembering self and short-term well-being of the experiencing self.
