Ego - a motivating force

"All top salespeople have ego," Zain preached. "I have an ego."

Why do salespeople endure rejections even though they can get other jobs in calmer waters? I summise that to the top salesperson, getting someone to say yes provides a powerful means for ego enhancement.

I have learned from dealing with close to 100 salespeople that the salesperson with an overabundance of ego-drive can, if mixed with other qualities, be exceptionally successful.
