There are a few other principles in decision making
There are a few other principles in decision making. One of them is called occams razor which urges you to not focus on complex theories and ideas and potential outcomes but rather focus on the simplest one which is usually a better one. This also saves time. There is another principle called Hanlon's razor which urges you to not look at any causes of problems as the fault of anyone but rather the lack of knowledge. This helps you avoid placing blame on another person and helps you focus on making the decision.

In the book
Then aim high — reaching for the large costs no more than reaching for the small. 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. — The Flight Plan (Purpose/Wisdom/Risk)
