Good talent with bad attitude equals bad talent.

"Extra effort," in whatever form it takes (mental, physical, emotional), cannot be sustained without eventual damage and diminishing returns. There has to be a very acute awareness on your part as to the level of exertion and the toll it's taking on those you lead.

I often think about the class differences involved in "jobs" vs. "careers."

Strength of will - is essential to your survival and success. The competitor who won't go away, who won't stay down, has one of the most formidable competitive advantages of all. In evaluating people, I prize ego. It often translates into a fierce desire to do their best and an inner confidence that stands them in good stead when things really get rough. Psychologists suggest that there is a strong link between ego and competitiveness. All the great performers I've ever coached had ego to spare.

When I give a speech at a corporate event, I often ask those in attendance, 'Do you know how to tell if you're doing the job?' As heads start whispering back and forth, I provide these clue: 'If you're up at 3 A.M. every night talking into a tape recorder and writing notes on scraps of paper, have a knot in your stomach and a rash on your skin, are losing sleep and losing touch with your wife and kids, have no appetite or sense of humor, and feel that everything might turn out wrong, then you're probably doing the job.'

Failure is part of success, an integral part. Everybody gets knocked down. Knowing it will happen and what you must do when it does is the first step back.
