There is a fable about a little girl who was feeling particularly lonely and blue when she happened across a gorgeous butterfly trapped in the thorns of a blackberry bush. Taking great care not to tear its fragile wings, the girl's nimble fingers finally worked the insect free, whereupon, instead of fluttering away, it turned into a golden fairy who offered to grant any wish.

"I want to be happy!" the little girl cried.

The fairy smiled, leaned forward, whispered something in her ear and vanished. And from that day forward, there was no more happy spirit in the land than that child, who grew into a merry woman and a contented old lady. On her deathbed, her neighbors crowded around, desperate that the secret of happiness not die with her.

"Tell us, please tell us, what the fairy said to you," they pleaded.

The neighbor smiled benevolently, and whispered, "She told me that everyone -- no matter how rich or secure or self-contained or successful they might appear -- had need of me."

How true! Everyone needs to be needed. It brings tremendous satisfaction to know that you have a vital purpose in life, one that surely contributes to your happiness and contentment.

I've learned over the years that happiness comes from making other people happy. Successful people, as well as successful businesses, take great joy in finding ways to spread happiness. Why is Disneyland the "happiest place on Earth"? Is it any wonder that one of the biggest songs of the year is Pharrell Williams' "Happy"? How many Happy Meals do you think McDonald's sells? Have you ever attended a happy hour at your favorite watering hole?

Businesses that are clued in to what customers want find ways to incorporate "happy" into the sale. A new car doesn't drive any better because the dealership was decked out in balloons and offered free hot dogs. But a happy experience beats an ordinary one, most days.

Following that line of thought, it turns out that the conventional wisdom is wrong: It is possible to buy happiness -- when you spend your money on others. Researchers at the University of British Columbia and Harvard University found that people who buy gifts for others and make charitable donations report being happier than people who spend their money primarily on themselves. The scientists studied 630 Americans and asked them to rate their general happiness, their annual income and their monthly spending -- including bills, gifts for themselves, gifts for others and charitable contributions.

And again, it illustrates the point that knowing that others have need of you brightens your outlook.

Even our nation's Declaration of Independence places a premium on happiness, stating that we are "bestowed with certain unalienable rights, which among these are life, liberty and the pursuit of happiness." Thomas Jefferson and company left it up to us to figure out how to pursue happiness, but I have some thoughts for you. Here's my prescription for happiness. Use it regularly and you will see wonderful results.

1. Don't let little things bother you. There is always something better to think about.

2. Keep your perspective. Put first things first and stay the course.

3. Only worry about what you can control. If you cannot do anything about a situation, worrying won't make it -- or you -- better.

4. Do your best, but understand that you can't always be a perfectionist. Don't condemn yourself or others for not achieving perfection.

5. When you are right, be gracious. When wrong, be even more gracious.

6. Trust or believe people whenever you can, and when that isn't possible, accept them at their worst and weakest. You can keep your convictions without destroying others.

7. Don't compare yourself to others, which guarantees instant misery. People are different for many reasons.

8. Brush away the chip on your shoulder so that when something happens to you that you don't like, you can take the high road.

9. Give of yourself wholeheartedly or enthusiastically. When you have nothing left to give, someone will return the favor.

10. Make happiness the aim of your life instead of bracing for life's barbs.

11. Remember, you are responsible for your own happiness. Others can do kind things for you, but you must be open to being happy. But don't let that stop you from trying to make others happy!

Mackay's Moral: You are only as happy as you decide to be.

I began a second or third career as a motivational business speaker about 26 years ago. Several times a month, I have the privilege of speaking to a Fortune 1,000 company, offering business advice and inspiring stories to stir people to capitalize on their abilities and reach their full potential.

I love this part of my job. I've met thousands of people who are looking for help getting started -- a little extra motivation. But what they perhaps don't understand is that while I may be a good storyteller and enthusiastic cheerleader, the motivation doesn't actually come from me. It's the "fire in the belly" of the listeners that will eventually determine whether they achieve more than they thought they could.

That's right -- motivation must come from within. You have to ignite your own passion. Otherwise, how do you explain that in a roomful of people who hear the same message, some will just go back to the office, grateful for the break, while others go on to accomplish great things.

I am fascinated with the science of what makes people tick. Let me share an example from a pioneering thinker in the field of workplace motivation, David McClelland, who developed many of his theories in the 1950s and '60s.

With no stipulated rules, volunteers were asked to throw rings over pegs just like in the carnival game. Most people seemed to throw from arbitrary, random distances, sometimes close, sometimes farther away. But a small group of volunteers, who McClelland suggested were strongly achievement-motivated, carefully measured and tested distances that would produce a challenge that was not too easy, but not impossible.

McClelland identified the need for a "balanced challenge" in the approach of achievement-motivated people. People with strong achievement motivation need to set themselves challenging but realistic goals.

That makes perfect sense to me. I have an easier time getting motivated to sell to an account that I have a reasonable expectation of landing, even if it takes several -- or many -- calls. I can talk myself into going back again and again if I want it bad enough, and if I think I have a chance of success.

As humorist Oscar Wilde put it, "My great mistake, the fault for which I cannot forgive myself, is that one day I ceased my obstinate pursuit of my own individuality." In other words, the day he lost motivation to be his best self.

My friend Brendon Burchard has set out a plan that demonstrates how to avoid that trap. His new book, "The Motivation Manifesto: 9 Declarations to Claim Your Personal Power," is based on the theory that "a vibrant, genuine, and purposeful life is the right of all humankind. ... Humankind's main motivation is to seek and experience personal freedom."

Personal freedom, he says, is important because "when controlled by others, life loses its flair, and we are cast into melancholy and mediocrity."

That sounds to me like the opposite of motivation. So we need to be free to be motivated. But, Burchard says, that presents a difficult choice, "between the comforts of fitting in and pleasing others and our higher motive for personal freedom."

He says: "To achieve personal freedom, we must dedicate ourselves to self-mastery; we must determine and discipline our own motivations to stay true to our sense of self, to our own path."

Overcoming fear -- specifically fear of failure -- is essential to freedom. Burchard encourages readers to repeat this mantra: "Fear wins or freedom wins, and I choose freedom."

And perhaps his boldest statement is this: "Our entire human value system rests on motivation. None of the great human values that keep us and society in check -- kindness, love, honesty, fairness, unity, tolerance, respect, responsibility -- would flourish if we were not motivated to bring them to life."

Sustaining motivation requires real effort. In order to claim the personal power required for motivation, Burchard presents and expands on these nine declarations:

-- We Shall Meet Life with Full Presence and Power

-- We Shall Reclaim Our Agenda

-- We Shall Defeat Our Demons

-- We Shall Advance with Abandon

-- We Shall Practice Joy and Gratitude

-- We Shall Not Break Integrity

-- We Shall Amplify Love

-- We Shall Inspire Greatness

-- We Shall Slow Time

Motivation is a daily challenge. But understanding the rewards makes the effort worthwhile.

Mackay's Moral: (with thanks to Chinese philosopher Lao Tzu) "When I let go of what I am, I become what I might be."
