I've always considered myself quite bold when it comes to business and risk-taking. I can live with failing a few times, knowing that I will eventually be successful because I am determined to be.

I've found a like-minded colleague in Jeffrey Hayzlett, host of Bloomberg Television's "C-Suite With Jeffrey Hayzlett" and author of an inspirational new book, "Think Big, Act Bigger."

Hayzlett embraces big and bold without apology or inhibition. "Thinking big and acting bigger is all about action and attitude: being fearless and bold, steamrolling obstacles, ignoring perceived limitations, and even being a little irrational and pigheaded at times," he writes. "I've learned it is about being relentless in all I do but especially trusting in who I am because I can."

He shared an important philosophy in an earlier book, "Running the Gauntlet," where he wrote: "No one is going to die from changes you make in business." He has since refined that idea, but the importance of the message remains.

He shares five important lessons in that vein:

-- No one is going to die when you think big and act bigger, so get over yourself.

-- Stop overthinking things, coming up with reasons not to do something and then playing it safe. You still might fail. And that's OK.

-- Succeeding fast is better than failing fast: Stop wearing failure as a badge of honor.

-- Passion fuels that momentum and drowns out the negative voices in your head.

-- Passion can override your fears and inhibitions, but it cannot override facts. Yet it can also lead to overindulgence, obsession and lost perspective.

"Passion comes from our hearts and guts, not our heads," he continues. "It's a strong emotion and can lead us into bad decisions and questionable actions. But it is the adrenaline we need to succeed."

My opinion is that it's OK to be passionate, but you better be good at what you're passionate about.

Hayzlett says successful leaders have to strongly identify with what they don't want as well as what they do want. Being genuine in character makes people willing to follow them even when they are pigheaded or irrational.

Does that ever strike a chord with me! As long as people know what to expect from me and I live up to my ideals, I can honestly say that while my staff may wonder what I am up to, they support my actions almost 100 percent of the time. They assume I have some information or experience that is guiding my decisions. That's how you earn trust, and it's critical that you don't abuse it.

Hayzlett's friend Greg Lucier, the former CEO of Life Technologies, introduced him to the term "irrational leadership," explaining that you have to be so far out there sometimes to pull people along to where you want them to go. Hayzlettt writes: "I had said for years that leaders need to create tension and results by pushing farther and farther to move the rest of their teams in that direction. Now I had a name for it."

"Think Big, Act Bigger" is full of no-nonsense lessons that even successful leaders should study and review to keep their perspective. One of my favorites is the following story, which Hayzlett tells in a chapter about the importance of maintaining a constant state of awareness: On a fishing trip to Canada, Hayzlett's guide served a specific brand of blueberry jam, which came in a can, and which he liked so much that he bought a case and shipped it home to South Dakota at a very high price.

His wife was stunned. Why would he do that? Despite his best explanation about the special jam, she was unimpressed and teased him about it over the next couple of weeks.

On a trip to their local supermarket together, she needled him again about his expensive purchase. He responded, telling her that she really didn't understand how special this jam really was. The clincher: "You can't get this anywhere else ..."

And that's when she told him to turn around. There, on the shelf, was his prized jam -- for $2 a can. A constant state of awareness, indeed!

It's getting easier and easier to navigate the highways and byways through the magic of GPS -- the Global Positioning System. The service is in your car, your phone, your tablet, your watch. You are running out of excuses for not getting to where you want to go.

Wouldn't it be great if such a tool existed for finding your way through life's challenges? If you're like most ambitious people, you're always trying to get more done. The secret is paying attention to what you want to achieve. You can devise your own GPS formula by changing the words just a bit.

G is for goals. Make a list of what you want to accomplish so everything is clear and detailed in your mind. Make sure your goals are specific, including deadlines for completion and your measurements for success. Don't overload yourself. Concentrate on just one or two objectives at a time.

Goals give you more than a reason to get up in the morning; they are an incentive to keep you going all day. Goals tend to tap the deeper resources and draw the best out of life.

Most important, goals need to be realistic -- beyond your grasp but within your reach in the foreseeable future. Achieving goals produces significant accomplishments.

I remember a particular Peanuts cartoon in which Charlie Brown is having a bad day. He has struck out for the third straight time in a baseball game.

Back in the dugout, he buries his face in his hands and tells Lucy how he will never achieve his dreams of becoming a big-league ballplayer.

Lucy tells him that he's thinking too far ahead and needs to set more immediate goals. When Charlie Brown asks for an example, she tells him to see if he can walk out to the pitcher's mound without falling down.

P is for plans. Work out a general plan for achieving each goal over the long term. For instance, if you want a high-level position in your organization, your plan might include earning one or two intermediate promotions, getting additional training or volunteering for specific important committees. Each phase in your plan is a goal in itself. Approach each interim goal methodically, and follow a consistent process for completing each one.

People don't plan to fail; they fail to plan.

Try a process that I often use: working backward from the goal. If you want to arrive at Point X within a certain timeframe, you need to think about what you have to achieve to get there. That leads to your "S."

S is for segments. Break your plan down into separate segments that are small enough to tackle one after another, and large enough to stretch your skills at least a little. Think in terms of what you can accomplish in a single day, where you want to be at the end of the first month and so forth. This gives you a sense of direction and also helps you monitor progress.

Your personal GPS is not an app or option. It is basically standard equipment that doesn't cost extra. But you'll pay dearly if you don't activate it.

You can achieve your goals. But there's one catch. You have to commit to actually taking those steps and sticking to your plan. Staying motivated can be challenging, but keep your eye on the prize. Visualize your new business card, your corner office, your dream vacation ... whatever marks the achievement of your goal.

Otherwise, you'll just be another Marvin. Marvin dreamed of winning the lottery. Every time there was a drawing, he prayed loud and long that he would win. One day, as Marvin was beseeching the Almighty, the clouds parted and a voice boomed out from the heavens. "Marvin, Marvin," the voice said.

"Is that you?" gasped Marvin.

"It is I," intoned the voice.

"Are you here to answer my prayer? Will you let me win the lottery?"

"I will," said the voice, "but you have to meet me halfway. Marvin, buy a ticket!"

Buy your ticket. Set your goals. Follow your plans. Make your steps. Then take them out and look at them often. That's the only way you will achieve them.

Mackay's Moral: Life is full of detours, but you can always get back on track if you use your GPS.

The only survivor of a shipwreck woke up on the beach of an uninhabited island. Every day he circled the island, looking for ships on the horizon, and searched the sky for planes, hoping for a rescue. But none ever came.

So he scrounged around for materials to build a small hut to protect himself from the elements. His daily schedule included scavenging and hunting for food. He kept a small fire going so he could cook whatever he found.

After his walk around the island one day, he returned to find his hut in flames. A gust of wind had blown some embers from his fire, which had ignited the hut. Black smoke billowed through the air. Try as he might, he couldn't douse the fire. He collapsed, exhausted and dejected. He had lost all hope.

But the next day he awoke to find a ship anchored off the island. He would be rescued at last!

When he reached the ship, he asked the captain, "What made you stop here? I have been looking for a ship for months and saw none."

The captain replied, "We saw the smoke from the fire you built. It led us right to you."

What had seemed hopeless was what saved him.

Hope sees the invisible, feels the intangible and achieves the impossible. In short, hope changes everything.

My dear friend Lou Holtz always said you need four things in your life: No. 1, everyone needs something to do. No. 2, everyone needs someone to love. No. 3, everyone needs someone to believe in. And No. 4, everyone needs something in his or her life to hope for.

What do you want to do? You have to have hope, ambition and dreams.

My wish, dream and hope, aside from being a professional golfer, was to own my own factory. I didn't know what I would manufacture, but I always hoped to be able to walk the factory floor and have my employees look up to me.

But I didn't wait for it to fall in my lap. I acted on that hope and made my dreams come true.

Just because something isn't happening for you right now doesn't mean it will never happen. Hope is the little voice you hear whisper "maybe" when it seems the entire world is shouting "no."

Believing in the future helps us to have hope. "Hope is greater than history," said American businessman and diplomat Dwight Morrow more than a century ago. Don't let the idea that history repeats itself discourage you. You can shape your own history if you have hope.

Consider these words from naturalist Jane Goodall: "I carry a few symbols with me because sometimes you get a bit depressed, and these symbols remind me of the hope that there is in the world. ... I carry symbols that represent four reasons for hope: the human brain, with the technology that we are now working to try to live in greater harmony with the environment; the resilience of nature -- give nature a chance and it's amazing how places that we've destroyed can bloom again; the tremendous energy, commitment, excitement and dedication of young people once they know what the problems are, and we empower them to act to do something about it. And finally, the indomitable human spirit, those people who tackle impossible tasks and won't give in, those people who overcome tremendous physical disabilities and lead lives that are shining inspiration to those around them."

Mackay's Moral: Hope is what allows us to remember yesterday's disappointments and still look forward to tomorrow.
