The smarter you get, the less you speak.
Sometimes you have to bite your tongue. There is no point in arguing with someone who wants to bring you down to their level. A strong person knows when to speak, when to talk and when to move on. They don’t have time for silly arguments with those lower than them. Make the other person sit with what they said. Leave them wondering what you’re thinking. Arguing is an immature move made by losers. Keep your mouth shut and learn more.
