Early in my career I had the good fortune to report to a leader who inspired great ideas from everyone in our department. When someone presented an idea to Dan, his ready response was, "My green light is on." And, we all knew he meant it.
He would lean forward. His eyes would twinkle. He'd tilt his head, look you in the eye, and, in a tone bordering on glee, he'd say, "So, tell me more about this idea you have." It was downright exciting to present your ideas to Dan.
