Two in five Americans dream about the day they can tell their boss they quit, according to a new survey-but it's not necessarily because they hate their job. Instead, it's because 67% have dreams of being an entrepreneur.

And, people really do feel their ideas could change the world - results show that, of those who aspire to open a business, 68 percent believe their idea would be revolutionary for the industry.

The international survey of 23,500 respondents - spanning 24 countries and including 2,000 Americans - looked at the entrepreneurship dreams of people around the globe, as well as their motivations and the challenges they face.

Across the globe, the top reason to start a business was found to be following a passion (64%).

For Americans, other reasons included being their own boss (59%), supporting their family (51%), and wanting to solve a problem/improve the world (36%).

Commissioned by Herbalife Nutrition and conducted by OnePoll, the survey found that 52% of aspiring American entrepreneurs have already taken steps to open their business.

But that doesn't mean there's any easy road in front of them: With all the barriers business owners face, 81% of Americans interested in starting a business feel overwhelmed by the prospect-and compared to those in other countries, more are anticipating failure before starting. Three-quarters (76%) feel they may never have the opportunity to follow their dream, compared to 69% globally.

The biggest barrier to entrepreneurship across the globe was found to be the initial cost of opening a business (65%). Other barriers to opening a business include fears of profitability (38%) and a lack of financing/marketing knowledge support (38%).

But, 3 in 10 aspiring American entrepreneurs were unsure even of which steps to take in order to start.

Of those who currently own a business, 41% took the leap after having a dream, listening to their gut, or being encouraged by family.

From the initial idea to actually starting the business, it took respondents an average of three years to implement their dream.
