Secrets of being a good teacher?

I was reminded again of this article in the Atlantic on good teachers after coming across the Haim Ginott's teacher quote in a classroom:

I have come to a frightening conclusion.
I am the decisive element in the classroom.
It is my personal approach that creates the climate.
It is my daily mood that makes the weather.
As a teacher I possess tremendous power to make a child's life miserable or joyous.
I can be a tool of torture or an instrument of inspiration.
I can humiliate or humor, hurt or heal.
In all situations, it is my response that decides whether a crisis
will be escalated or de-escalated, and a child humanized or de-humanized

The Atlantic article tries to summarize the findings into something that can be implemented:

First, great teachers tended to set big goals for their students. They were also perpetually looking for ways to improve their effectiveness. For example, when Farr called up teachers who were making remarkable gains and asked to visit their classrooms, he noticed he’d get a similar response from all of them: “They’d say, ‘You’re welcome to come, but I have to warn you—I am in the middle of just blowing up my classroom structure and changing my reading workshop because I think it’s not working as well as it could.’ When you hear that over and over, and you don’t hear that from other teachers, you start to form a hypothesis.” Great teachers, he concluded, constantly reevaluate what they are doing.

Superstar teachers had four other tendencies in common: they avidly recruited students and their families into the process; they maintained focus, ensuring that everything they did contributed to student learning; they planned exhaustively and purposefully—for the next day or the year ahead—by working backward from the desired outcome; and they worked relentlessly, refusing to surrender to the combined menaces of poverty, bureaucracy, and budgetary shortfalls.

.... one way that great teachers ensure that kids are learning is to frequently check for understanding: Are the kids—all of the kids—following what you are saying? Asking “Does anyone have any questions?” does not work, and it’s a classic rookie mistake. Students are not always the best judges of their own learning. They might understand a line read aloud from a Shakespeare play, but have no idea what happened in the last act.
“Strong teachers insist that effective teaching is neither mysterious nor magical. It is neither a function of dynamic personality nor dramatic performance,” Farr writes ...

I am struck by the differences between the substance and the imagery in the Ginott quote and what we need to do to improve student performance.
