It’s a Mental models to identify which systems (contexts, activities) in our life that are worth optimizing using First-principles thinking.

  • Try to raise salary 15%
  • Swap jobs and increase salary by 25%
  • Is my end goal something outside the professional realm? What if I reduce living expenses so I don’t have to work to climb the corporate ladder
