Teamwork, good relationships and creativity are key to business success

There are three simple rules in life:

If you do not go after what you want, you'll never have it. If you do not ask, the answer will always be no. And, if you do not step forward, you'll always be in the same place.

I can't take credit for these maxims: the author Nora Roberts came up with them. But they started me thinking about my own life and everything that I've learned over many decades in business. Several guiding principles help me make decisions, plan strategy and sleep at night.

For example, I know that you have to dig your well before you're thirsty. I believe it so completely that it became the title of my book on networking. Here is the most important line: "If I had to name the single characteristic shared by all the truly successful people I've met over a lifetime, I'd say it is the ability to create and nurture a network of contacts."

In the end, it's not the amount of money that you make or the buildings that you own that matter. It's the people on whom you can depend — and who can depend on you — who make your life better.

A close second for the top lesson of my life would be the following: "People don't care how much you know about them, once they realize how much you care about them." It's so important I made this the theme of my first book. It's also central to my Mackay 66 Customer Profile, which is the cornerstone of all my speeches.

You have to learn as much about your customers and suppliers as you possibly can, because you can't talk about business all your life. You have to build those relationships and take it from a business level to a personal level. Knowing something about your customer is just as important as knowing everything about your product.

Another key lesson: "Believe in yourself even when no one else does." I have never met a successful person who hasn't had to overcome either a little or a lot of adversity in his or her life. So, who says that you can't accomplish your goals? Who says that you're not tougher, better, smarter, harder working and more able than your competition? It doesn't matter if they say you can't do it. The only thing that matters is if you say it.

Next, I've learned that we can't go it alone. What is teamwork? It's the product of a collection of people who respect each other and are committed to each other's successes. The beautiful part of teamwork is that it offers us the opportunity to use our own special talents and abilities.

The last thing I'll mention, and the way I finish all of my speeches, is to put some fun and creativity into your business and life. You can take your work seriously, you can take your relationships seriously, but you should never take yourself too seriously.

Supremely confident people worry very little about being the coolest, smartest, most admired person in the room. They understand that by putting others first, they move to the front of the class. They have truly learned some of life's most important lessons.

In the end, we only regret the chances we didn't take, the relationships we were afraid to have and the decisions we waited too long to make. Learn from your mistakes. Be grateful for second chances and forgiving friends.
