Questions are a sign of intelligence and curiosity
Did you think in school that if you asked a question you were admitting you didn’t know something you were supposed to know?
It’s the opposite. You care about understanding. You want to know. You have interest. You are curious to understand at a deeper level. Maybe you are making sure you got the instructions straight.
Einstein claimed it was curiosity, not intelligence, that made the difference and made him able to discover and make such strides in science and mathematics.
Hopefully no one ever told you to stop asking questions.
