When teaching, it is crucial to consider the value of what you are about to say before interjecting. If it does not contribute to the conversation, it should not be said. Albert Einstein emphasized the importance of simplicity in understanding - if you cannot explain something simply, you do not understand it well enough. Similarly, Seneca suggests that teaching should be done patiently, quietly, and simply. Shouting authoritatively or delivering long speeches is not an effective way to teach. Providing more information does not necessarily lead to better learning, and in fact, simplicity can aid in better understanding.
