I would say that IQ is the strongest predictor of which field you can get into and hold a job in whether you can be an accountant lawyer or nurse for example.
But once you are in that field emotional intelligence emerges as a much stronger predictor of who will be most successful because it is how we handle ourselves in our relationships that determines how well we do once we are in a given job.
Divorce is one of the key predictors of poverty for a child growing up in a home that's broken.
I played it right because that's what you're supposed to do - play it right and with respect.
