When you speak, you are just repeating what you already know.
But if you listen, you may learn something new.

Of Course my dear, your idea is good but some people have habit talk, about any thing  without any think😒

but speaking alone for yourself may even remind you the lessons you’ve learned from the past.

Yes, it's exactly the same. I agree with you. When a person listens and concentrates on what is being said and seen, all that content and what is seen is recorded in his long-term memory, but when you just talk without concentrating, you will definitely not learn anything.
