Independent advisors are small business owners. Often, the skills that help them succeed as producers do not translate to running a business.

And they are not alone. According to Gallup, half of new U.S. companies fail in their first five years. It gets worse. The failure rate hits 70 percent in the first 10 years.

“That’s not surprising,” says Randy H. Nelson, an entrepreneur who has built multi-million dollar companies. “The skills it takes to start a business aren’t necessarily the same as those it takes to keep that business afloat.” What is surprising, though? In the U.S., more businesses are now being shut down (470,000) than are being started (400,000).

“Many entrepreneurs have the gumption to take that dramatic first step of sparking something into creation, but too many lack the perspective to reflect on what’s needed for the next step,” says Nelson, author of “The Second Decision – The Qualified Entrepreneur.”

Nelson says entrepreneurs often make five mistakes that threaten to put their businesses at risk.

Insistence on autonomy. An Inc. Magazine study once said that a trait most entrepreneurs share is their desire for autonomy, which is great starting out, Nelson says.

But after the startup phase, the company steams into the growth phase, becoming more complex and more vulnerable to industry and economic trends. At that point, an entrepreneur’s insistence on autonomy can hinder the company’s ability to respond quickly and intelligently to challenges it faces. “In the growth phase, you simply can’t do it all, and it’s foolish to keep believing you can,” Nelson says.

Unwillingness to build structure, cultivate expertise or delegate. Many entrepreneurs will need to surround themselves with a strong executive team— or at least a steady right-hand individual—to ensure the company’s success, Nelson says. But too many business owners fail to create the kind of structure that produces good leadership decisions within a managerial team.

“As you grow your company and enlarge it to meet new opportunities, you must also build in accountability,” Nelson says. The entrepreneur needs to know the employees and where their strengths lie to put them to good use, he adds.

Lack of financial leadership. Entrepreneurs by definition take risk when they make the decision to start their own business. In the area of financial leadership, which includes tracking cash levels and trends, financial covenants, metrics and expenses, entrepreneurs who are not financially literate and active will need the direct support of a financial expert to ensure they receive the advice and input needed in their organization.

Nelson says: “When it comes to financial leadership, it is what entrepreneurs don’t know that they don’t know that will multiply the risk in their business exponentially.”

Reacting unwisely to boredom. A bored entrepreneur can create significant troubles for the business, Nelson says. “Things are going to get up-ended in a hurry, because many bored entrepreneurs either start new companies or abruptly make changes in their current companies to keep their own level of excitement high,” he says.

“Of course, entrepreneurs are to be celebrated for their guts and desire to innovate. But when a serial entrepreneur habitually and almost obsessively looks for new sandboxes to play in, what happens to the existing company or companies often isn’t very good.”

Failure to engage in self-examination. Entrepreneurs need to be aware of their own strengths and weaknesses, the same things they gauge in their employees.

“You need to set aside your probably abundant self-confidence and take stock of what you know, what you’re good at, and what skills you still need to master in your leadership role,” Nelson says.
