A friend taught me a great lesson in how people with higher status behave compared to people with lower status.
Here it is as a piece of advice
What you can say in many words, say in few.
What you can say in few words, say with a gesture.
What you can say with a gesture, say with a subtle gesture.
These words give great advice while describing the effectiveness of body language over words and subtlety over rambling.
Next time you find yourself talking a lot, realize you’re undermining yourself. Next time you’re with someone whose status is much higher, notice their behavior. Notice yours when you have the higher status.
Notice how people respond to you when you follow the advice. I bet you’ll find it dramatic.
