Asking questions is not only a trait of smart people, but it is quite possibly the simplest most effective tool that can set you appart in many things.

Think about the last time you bought something where you had a great sales experience. How many questions did the sales person ask? Think about last time you were on a great date? Did the person ask questions about you.

Asking questions is a sign of validated learning and active listening and those two concepts are the way we better ourselves and our surroundings.
