RUL3 - Love bad news. Always question to falsify your idea and theory. Invalidate ASAP. How fast you can invalidate matters as much as how fast you can build them. Rule out bad explanations.

3-1b1a1 People think big ideas are answers, but often the real insight is in the question. The question-answer categorization is arbitrary.
1-1c4b You always have to solve problems, including the problem of what problems to solve
3-1b1 Occasionally revisit the problem itself. Occasionally check in on long-term.

1-2f1b4 The content of a theory is in what it rules out (and how!)

It’s about how to find the right questions as fast as you can
