"Do not talk a little on many subjects, but much on a few"

Pythagoras was a Greek thinker and mathematician who lived in the 6th century BC. He is best understood for his theorem about the sides of a right triangle. In this quote, he is motivating people to focus their discussions on a couple of subjects rather than talking a bit about various topics. He is suggesting that it is much better to have a deep understanding of a couple of topics than a shallow understanding of numerous. This guidance is still relevant today, as it is necessary to be able to have meaningful discussions and to be able to talk about subjects in depth. By focusing on a couple of subjects, we can gain a better understanding of them and have the ability to have more meaningful conversations. This quote is a suggestion to concentrate on a couple of subjects and to pursue a deeper understanding of them.
