When you think about the highest earning business coaches, people like Ali Brown and Carrie Wilkerson and Marie Forleo, what comes to mind? Charisma, experience, and expertise are often at the top of the list, but would it surprise you to know that those are not the most important characteristics?

In fact, while those things do help attract and keep an audience, there’s one thing that is absolutely critical to their success, and you can’t even see it.

Mindset.

It’s true. In everything you do, whether in business or in life, your mindset is the determining factor when it comes to your success. Your coaching plans are no different. Without the right mindset, you will forever be attracting and working with clients who—while deserving and lovely—are less than your ideal when it comes to their ability to pay.

So before you can realize your dreams of four- or five-figure clients, you have to do some internal work. You have to make some changes to your own mindset, to be more in line with what the top earners in your industry already do and feel.

Changing Your Attitude

One thing charismatic and personable people have in common is a good attitude. Think about it; you’ll never see Carrie Wilkerson or Paul Evans complaining about how the kids are sick, “again!” or that the cable repair guy is 40 minutes late, or even that the car blew a tire.

Instead, you see their expressions of gratitude in everything. If the kids are sick, they’re grateful to have a business that allows them to stay home and play nurse. If the cable guy is late, they’re grateful to have 40 extra minutes to read a book instead of watch television. And if the car died in the middle of running a week’s worth of errands, they’re happy to have found a mechanic who does great work at a reasonable price.

If you find yourself complaining—even in your head—turn your attitude around. There’s nearly always something to be grateful for, even in the worst situations. And when you can rethink and revise your attitude for the better, you’ll not only be happier, but you’ll attract a better audience, too.

Growing Your Confidence

Here’s something else top-end coaches have in common: confidence. They believe in what they do. They believe in their ability to help others achieve the same thing. They walk on stage or join a webinar filled with the knowledge that what they are about to say will change the lives of those who are listening.

It’s not cocky or arrogant, it’s just confidence. And if you don’t have it yet, you can take steps to increase it.

Start by asking yourself, in any new or uncomfortable situation, “What’s the worst that could happen?” Of those worst-case scenarios, resolve what you have control over, and let the rest go. So if you’ve agreed to speak in front of a small group of business owners, and your fear is that you’ll flub your speech, practicing beforehand will greatly improve your confidence.

Next, get inside the head of someone who is confident in what you’re about to do. Walk onto that stage as if you’ve been doing it for years, and not only will you feel more confident, but you’ll be more confident. You can use the “as if” attitude in everything from creating a new product to closing a sale. Whenever you feel your confidence failing, just remember to act as if you’ve done this successfully hundreds of times.

Just like how the person you’re talking to on the phone can hear a smile in your voice, your potential clients can sense your mindset. And if it’s not up to the standards of the top earners in your niche, you’ll struggle to make the sale. Work on your attitude and confidence levels, and watch your income soar.
