If you're sitting on a game-changing business idea, you're not alone. According to data from Northwestern Mutual, over half of Houstonians surveyed said they they've got something up their sleeves for a startup — and a third of that group said their idea has the capability to change the industry.

Of the respondents who said they had a business idea, almost 60 percent have already taken first steps to making their idea a reality. But for those yet to take a plunge, the factors holding these aspiring entrepreneurs back were primarily financial. More than 60 percent said not having enough finances were what's stopped them from taking the next step, while over a third indicated that they weren't sure what their next step would be. About 30 percent identified the fear of failure as what's held them back.

Similarly, when asked what the biggest hurdle in starting a company for their business idea, almost half of those surveyed said financial support, followed by "making money" with 17 percent. Of course, that's what Carrie Neumann, director of Multicultural Market Strategy at Northwestern Mutual, expected. Enter: Northwestern Mutual's financial advising services.

"A personalized, holistic plan sets business owners on track to achieve their goals, and it also puts protections — for the business, the owner and current or future employees — in place for the expected and unexpected," says Neumann in a release.

"For entrepreneurs, a trusted financial adviser is not only a great resource for the many questions that come up when starting a business, but an adviser can also help plan for the longterm."

Northwestern Mutual conducted a survey in partnership with OnePoll with a sample of 8,000 individuals in the United States. Houston was one of the 12 major metros included in the survey — and the lone Texas city. The other cities included in the survey were Chicago; Cincinnati; Denver; Miami; New York; Los Angeles; Omaha, Nebraska; Raleigh, North Carolina; Richmond, Virginia; San Francisco, and Washington D.C.

Houston skewed a tad more ambitious than the other metros surveyed. Across the sample, 41 percent of survey respondents said they have an idea for a business compared to Houston's 51.4 percent. Miami, New York City, and Los Angeles all had a higher percentage of respondents that said they had a great business idea. Los Angeles had over 60 percent of its surveyed participants respond affirmatively to that question.

The city of Houston has its advantages for entrepreneurs. A recent study shows that salaries stretch further in Houston, with the Bayou City ranking as No. 7 nationally. The study conducted by BusinessStudent.com factored in average pay of common jobs and the cost of living.
