Key points of life principles

Be a hyperrealist.
Be radically open-minded and transparent. Be radically open-minded starting from sorting out open-minded people from close-minded people then learn.
See from nature’s perspective: optimize for the whole and evolution.
Evolve (= adapt + determine + learn) fast to the pain.
Higher-level thinking. Learn thoughtful disagree, let the higher-level thoughtful you win out over the lower-level emotional you.
Be imprecise and an imperfectionist. “By and large” is needed to make efficient decisions.
Remember time axis and scale axis when synthesizing the situation at hand.
Thinking (simplify!) ⇒ Principles ⇒ Algorithms (believability weight, data-driven, etc.) ⇒ Great decisions.
