An important corollary is that school and tests teach you not to be wrong. They teach you that incorrect answers will be punished.

Yet, most interesting questions in life don’t yet have defined answers. Thus you need to have and test a hypothesis, which will very often be “incorrect” the first time around. But that doesn’t actually matter - the mere act of thinking about and defining what an answer could be sets you up to iterate and test. Eventually, you may find product market fit (a - not the - right answer).

You have to be willing to be wrong at first to learn...and win.
