Pressed to describe the stereotypical entrepreneur, which words would you use? Passionate? Dedicated? Optimistic? Sure, those apply. But insecure and troublemaker are more accurate, according to 'treps who know a success when they see one. Do the following traits, characteristics and quirks describe you? Well then, you might be an entrepreneur (at heart, if not yet in practice). 1. You take action. Barbara Corcoran, founder of The Corcoran Group, co-star of TV's Shark Tank and author of Shark Tales: How I Turned $1,000 into a Billion Dollar Business, says people who have a concept but not necessarily a detailed strategy are more likely to have that entrepreneurial je ne sais quoi. "I hate entrepreneurs with beautiful business plans," she says. Corcoran's recommendation? "Invent as [you] go," rather than spending time writing a plan at your desk. In fact, she believes that people with life experience have an active problem-solving ability and think-on-your-feet resourcefulness that can be more valuable than book smarts alone. Those who study business may be prone to overanalyzing situations rather than taking action. 2. You're insecure. "Many entrepreneurs judged as ambitious are really insecure underneath," Corcoran says. When evaluating potential investments, she adds, "I want someone who is scared to death." Those who are nervous about failing can become hyperfocused and willing to do whatever it takes to succeed. If you feel insecure, use that emotion to drive you to achieve your business goals. 3. You're crafty. "One of my favorite TV shows growing up was MacGyver," confides Tony Hsieh, CEO of Las Vegas-based Zappos, "because he never had exactly the resources he needed but would somehow figure out how to make everything work out." A lifelong entrepreneur, Hsieh has done everything from starting a worm farm to making buttons and selling pizzas, so he admires MacGyver's "combination of creativity, optimism and street smarts. Ultimately, I think that's what being an entrepreneur is all about--playing MacGyver, but for business." It's not about having enough resources, he explains, but being resourceful with what you do have. 4. You're obsessed with cash flow. Before founding Brainshark, a Waltham, Mass.-based developer of technology for business presentations, Joe Gustafson bootstrapped a venture called Relational Courseware. "All I ever thought about was cash flow and liquidity," he says, admitting, "there were seven times in [the company's] eight-year history when I was days or hours away from payroll and didn't have enough cash to make it." How did he respond? "In the early days, you could step up and put expenses on your personal credit card, but that can only go so far," he says. "You need cash--even if you have the best company and the best receivables in the world--to fight the battle one more day." Other strategies he recommends include working with a partner who can provide cash advances on projects and maintaining close communication with suppliers. 5. You get into hot water. Stephane Bourque, founder and CEO of Vancouver, British Columbia-based Incognito Software, says true entrepreneurial types are more likely to ask for forgiveness than permission, forging ahead to address the opportunities or issues they recognize, even without approval from higher-ups. "Entrepreneurs are never satisfied with the status quo," says Bourque, who discovered he was not destined for the corporate world when he kept coming up with new and better ways of doing things--ideas that were not necessarily appreciated by his bosses and often were interpreted as unwanted criticism. Now, he says, "I wish my employees would get into more trouble," because it shows they are on the lookout for opportunities to improve themselves or company operations. 6. You're fearless. Where most avoid risk, entrepreneurs see potential, says Robert Irvine, chef and host of Food Network's Restaurant: Impossible. True 'treps are not afraid to leverage their houses and run up their credit card balances in order to amass the funds they need to create a new venture. In some ways, he says, they are the ultimate optimists, because they operate under the belief that their investments of time and money will eventually pay off. 7. You can't sit still. Entrepreneurs have unbridled energy that fuels them long past the time when their employees have gone home. They are eager, excited and energized about business in a way that makes them stand out. Irvine would know: He owns a restaurant in South Carolina, is opening another in the Pentagon and has a line of food and clothing products, on top of hosting his TV show. 8. You're malleable. "If you have only one acceptable outcome in mind, your chances of making it are slim," cautions Rosemary Camposano, president and CEO of Silicon Valley chain Halo Blow Dry Bars. If you are willing to listen, your clients will show you which of your products or services provide the most value. Her original vision for Halo was part blow-dry bar, part gift shop, "to help busy women multitask," she explains. But she quickly learned that the gift shop was causing confusion about the nature of her business, so she took it out, replaced it with an extra blow-dry chair, and things took off. Smart entrepreneurs constantly evolve, tweaking their business concepts in response to market feedback. 9. You enjoy navel-gazing. Without direct supervisors, entrepreneurs need to be comfortable with the process of evaluating their own performance, says Laura Novak Meyer, owner of Pennsylvania's Little Nest Portraits. That requires "a willingness to solicit feedback from those around you to self-improve," she says, as well as paying close attention to feedback you may not have asked for, such as customer complaints or being outpaced by competitors. Little Nest surveys every client to ask for opportunities for improvement, and Meyer has worked closely with a business coach for the past five years to identify personal areas where she needs to improve.
