will learn more.
It means while studying if you know that you have to teach someone you
will study it hard and learn more.
Same apply to discussing. If you know you are going to discuss a
topic, you will make different connections and eventually when you
study you do put in the extra effort.
So if you want to learn a new topic, subject then think yourself as a
teacher. Or plan to discuss the subject with your peers.
Simple but effective!!
