Maturity is becoming less interested in appearing experienced and more interested in remaining teachable.

Wanting to seem experienced makes you defensive, since every gap in your knowledge becomes a threat to the impression. Staying teachable requires being willing to look like you do not know, which is uncomfortable and is the only way to keep learning past the point where you are already respected. Most people stop when the cost of appearing uninformed starts to feel too high.

Ask one genuinely basic question this week in a setting where you are expected to know. Notice that the ceiling does not fall in. The people worth impressing tend to be impressed by that rather than by the performance of certainty.
