  1. First-Principles Thinking, Made Usable
    First-principles thinking means breaking a problem down to the fundamental truths you are sure of, then reasoning back up from those — instead of reasoning by analogy to “how it’s usually done.” Traceable to Aristotle and popularized in modern form by figures like Elon Musk, it is a reasoning discipline, not a tested intervention; its value is mechanistic — it strips out inherited assumptions.
  2. Deconstruct the problem to its fundamentals
    Break the problem into the few things you actually know to be true, with no inherited conclusions.

  3. Reason up from the parts, not by analogy
    Build the solution from the fundamentals you kept, rather than copying an existing template.

  4. Use Socratic questioning to test each belief

  6. Prioritize direct experience over inherited belief

    The Perennial Philosophy, Made Practical
  7. The Perennial Philosophy, Made Practical
    The perennial philosophy, synthesized by Aldous Huxley from mystic and contemplative traditions across cultures, identifies a common inner core: a divine or ultimate ground underlying all existence, knowable through direct experience; an inner nature in humans capable of that knowing; and an ethics of love and compassion as the natural expression of that realization. It is not a scientific theory but a philosophical synthesis — its practices draw on contemplative traditions whose psychological effects have increasing observational and some experimental support.
  8. Train situational perception
    Before deciding, spend sixty seconds naming what kind of situation this actually is.

  9. Live what you study
    Make your practice your philosophy — not a separate reading life and a separate daily life.
    Philosophy as a Way of Life
  10. Question what everyone takes for granted
