According to an article in USA Today, a Dutch psychologist investigated the differences between chess masters and grand chess master.
He found no difference in IQ, memory or spatial reasoning.
The only difference he could identify: the grand masters simply loved chess more. He concluded that they had more passion about and commitment to the game.
I’ve observed that you don’t have to love what you do to be very good at it. I know very competent and successful individuals who have developed the skills to succeed at their work and who by their own admission see what they do as a means to an end. They don’t love their work, nor are they passionate about it. They are, however, very good at it.
But when it comes to greatness, I intuitively agree with the Dutch researcher. The inspired performers, the uber achievers and the grand masters of life seem to share a common difference. They simply love what they do a little bit more.
Love is the difference.
