I was struck by something Steven Spielberg said while receving the Cecil B. DeMille Award at the Golden Globes ceremony.
In talking about his very first movie (at 6, I think), he said he had a sense of "am I going to be able to get away with this?" And that feeling has followed him through every movie he's ever made. In fact, he said if the movie didn't make him wonder, "Am I going to be able to get away with this?" then he would pass on the project.
I'm grateful that I work for Group which has a culture of risk and innovation. And we've learned that when we do "play it safe" instead of pushing the envelope, we don't serve our customers as well.
I think greatness requires a big element of risk. Are you doing anything that makes you wonder "Am I going to get away with this?"
