How do ENTJs become likeable and less threatening to others?
The same way anyone would become less threatening: by looking at what makes them threatening, and adjusting.
How do you view ENTJs?
They're cool folks. I like spending time with anyone who's intuitive and enjoys order and logic. I haven't been exposed to too many ENTJs, but my girlfriend is XNTJ.
What would you like to see more of from ENTJs?
Nipple.
What could you do without?
Your questions.
