Mackay: Perfection is unattainable, but we must strive for it to achieve excellence

A young American singer taking a bow at La Scala in Milan was flattered when the discerning Italian audience forced him to return and sing an aria for the fourth time. Completely winded, he finally begged off, saying it was physically impossible to sing it a fifth time.

A voice boomed from the gallery, "You'll keep on singing it until you sing it right."

Setting high standards can inspire others and elevate the performance of your entire team, which is why you want to aim for perfection.

Perfection is not about never making mistakes; it's about learning from them. Each mistake is an opportunity to refine your approach.

Continuous improvement means to continually improve your skills and processes. It's about getting better every day.

Legendary pro football coach Vince Lombardi said: "Perfection is not attainable, but if we chase perfection, we can catch excellence."

Perfection is an aspirational goal, but our pursuit of perfection can drive us to achieve excellence.

The more prepared you are, the closer you get to that ideal of perfection in your pitches, presentations and negotiations. Yet follow-up is where many opportunities are won or lost. Striving for perfection in staying connected with clients can lead to more closed deals.

The trick is to balance perfection and practicality. You need to set realistic goals, be flexible and be satisfied with excellence. Otherwise you risk burnout and frustration.

Winston Churchill said, "To improve is to change; to be perfect is to have changed often."

Part of the journey requires you to regularly ask for constructive feedback from your peers, mentors and supervisors. Use this information to make adjustments and grow.

Embrace learning and accept that mistakes are part of the learning process. Each error is an opportunity to improve and refine your skills.

Maintain a healthy work-life balance. Rest and rejuvenation are essential for sustained high performance. My formula is this: Work as hard as you can, then give yourself permission to have some downtime. Then do it all over again.

Of course, loving what you do makes hard work much more rewarding.

Here's one last story to illustrate my point. Two men met on an airplane and began to talk. They asked each other the usual questions, and as it happened, one of the men was married and the other man was not. After a while, the married man asked, "Why is it that you never married?"

The single man looked pensive, then said, "Well, I think I just never met the right woman."

"Oh, come on," the married man replied, "surely you've met at least one girl during your lifetime whom you wanted to marry."

"Well, yes, that's true," he said. "There was one girl once. The perfect girl. Actually, she was the only perfect girl I have ever met. Everything she did was absolutely right on. She really was the perfect girl for me."

"Well, why on Earth didn't you marry her?" the married man asked.

"She was looking for the perfect man," the other replied.

Mackay's Moral: Nobody is perfect, but we are all perfectly capable of being awesome.
