What are your partner's deal-breakers? What are yours?

"Successful partners know who they are, who they aren't, what their struggles and blind spots are, and perhaps most importantly — they know their absolute bottom line deal-breakers.

"My wife, for instance, would never tolerate me even looking like I'm even approaching getting violent with her. I make a fist during an argument, and she'll be gone. Now, I've never been in a fight in my life, but this is not about me — this is about what she knows she cannot tolerate.

"And that's the point — great partners are actively working on self-awareness, and they actually use their partner's feedback to help them grow."
