Never talk to much.
Don’t be too chatty. Never interrupt people when they speak.
Talk less, listen more.
When you talk to much you give away everything: your plans, strategy, capabilities and fears. It is also un-masculine and unbecoming of a man to run his mouth. Each extra word that escapes your mouth is a chance to lose. It is a far greater accomplishment to listen well than it is to speak well.

Always be the last to speak. Let everyone else reveal their ideas and thoughts.
Listen, think then open your mouth. Let your voice be heard. You’ll always be the wisest man in the room if you are the last man in the room to open your mouth.

Do more listening than talking. Open your ears, close your mouth, listen…That’s how you win.
You never learn by running your mouth.
When you do speak, speak with complete authority.
