Possible first rule is know how to know yourself
Possible first rule is know how to know yourself. This means that that you need to identify your mind and thought processes that you use when You are thinking about yourself. Are you pulled in a certain direction? Are you honest? Are you willing and wanting to hear the opinions of others? In order to answer these questions you must be extremely reflective about yourself and ask yourself multiple questions. Make list. Questions like what do you enjoy? What do you want? How hard do you want to work for it? Many more. Create list. Reflect on how your mind works and what happens to you under and during different thought processes

In the book
Read the route with wisdom. Gather it from every person you meet, by the three roads Confucius named — reflection, imitation, and experience; prefer the simplest explanation that fits the facts, stay honest about what you do not know, and beware the man whose wisdom outruns his deeds, a tree with many branches and few roots that the first real wind topples. But before any of it, know yourself honestly — your strengths, your blind spots, your true motives. Accept the fare, and bound it. Take the risks your destination genuinely requires, asking of each whether it will give you skills and experience you'll keep, or open you to people and relationships worth having. — The Flight Plan (Purpose/Wisdom/Risk)
