Speaking positively and using words related to “insight” is associated with outstanding achievement.
That word “I” can be very telling. Powerful people don’t say it much. Less powerful people say it the most. People use “I” rarely when lying in order to psychologically distance themselves.
Couples who say “we” often when describing their relationships are more satisfied. Use of the word “you” is a bad sign. Using “we” can even predict whether you’ll survive a heart attack.
