There is a popular saying “those who can do, those who can’t teach”. Just because it’s popular doesn’t mean it has any truth to it at all.
Aristotle said “Those that know, do. Those that understand, teach”. While not as popular a statement, it has a lot of truth to it.
If you want people to understand a topic more, encourage them to help teach it. Figuring out the teaching process requires greater understanding of any topic.
Have a great day!
