How to Become an Entrepreneur: Leadership Lessons From an Unconventional Business Journey

Owning a business means owning the consequences

For Rosenthal, leaving corporate life was about more than becoming his own boss. It was about taking ownership of his life in a different way.

In a large company, leaders often spend time thinking about what a boss, board, or another department will say. Ideas can slow down as they pass through meetings, approvals, and competing opinions.

When you own the business, the decision is yours. That freedom can feel exciting, but it also comes with pressure. If the idea works, the win belongs to you. If it fails, the consequences do too.

This is one of the clearest examples of an entrepreneurial mindset. Entrepreneurs are not fearless. They simply accept that uncertainty is part of the process. They make decisions, learn from them, and keep moving.

What is an entrepreneurial mindset?

So, what is an entrepreneurial mindset?

An entrepreneurial mindset is the ability to see opportunity, take smart risks, solve problems, and learn from mistakes without stopping. It means being willing to act before every answer is clear.

Rosenthal showed this mindset when he looked at the barriers in healthcare and chose a simpler way to begin. He knew starting an insurance company would require large reserves, approvals, and years of red tape. Instead, he found a lower-cost entry point: mobile drug testing.

He bought a used RV because it had a bathroom for urine collections and planned to bring testing directly to employers. It was practical, affordable, and possible.

For anyone thinking about starting a business, that lesson matters. The best first step is often not the biggest idea. It is the idea you can actually afford to start, test, and improve.

Starting a business rarely follows the original plan

Rosenthal first imagined growing Health Street by adding more RVs. But as the company developed, he realized there was a better way. Instead of building a fleet of vehicles, Health Street became a centralized platform where companies could register online and schedule testing through a nationwide clinic network.

That shift helped turn a simple concept into a more scalable and successful business. It also shows why flexibility matters. Many founders begin with one idea, then learn from customers, operations, and market demand. The original plan may get you started, but the stronger business model often appears after you begin.

This is a major part of how to become an entrepreneur: start with what you can do now, then be willing to adjust when the market shows you a stronger path.

Bold business ideas often look risky before they work

At first, Health Street's truck had drug testing imagery. People noticed it, but not always in a positive way. As the company began offering DNA testing, Rosenthal saw a better marketing opportunity.

The "Who's Your Daddy?" DNA testing truck became one of the most memorable parts of Rosenthal's story. The idea was simple, funny, and risky: paint "Who's Your Daddy?" on the side of the truck.

Most people around him disagreed. Rosenthal said his own office voted against him 8 to 1. In a boardroom, the idea probably would have been rejected immediately. He did it anyway.

The result was instant attention. People honked, waved, took photos, and talked about it. Then the press came. The story landed in the media, and soon Rosenthal was speaking with major TV stations. It became an unexpected marketing strategy that helped the business stand out.

The lesson is not that every bold idea will work. The lesson is that successful entrepreneurs sometimes have to trust their instincts when the safe choice is also the forgettable one.

Choose your business structure carefully

Rosenthal did not want to build a company by pitching venture capital firms. He wanted independence, so he chose a business model he could afford. That decision shaped everything.

A founder who raises money may grow faster, but often answers to investors. A founder who self-funds may keep more control, but growth can be slower because the business can only reinvest what it earns.

Neither path is right for everyone. The important point is that structure matters. The way you fund and build your company affects your speed, pressure, decision-making, and long-term options.

For people researching how to become an entrepreneur, this is a practical takeaway: before you start, think carefully about the kind of business you want to own, not just the product or service you want to sell.

Leaving corporate status can feel like starting from zero

One of the hardest parts of Rosenthal's transition was the loss of status. In corporate leadership, a title carries weight. People return calls. Employees assume authority. Industry contacts see the role before they see the person.

Once Rosenthal left his executive position, some of that changed. People who once took his calls were no longer as responsive. Some questioned why he would leave a high-level role. Even hiring his first small team felt different from leading inside a larger organization.

This is a powerful leadership lesson.

Learn the work before you hand it off

Rosenthal also made an intentional choice to learn the work himself before hiring others to do it. He completed training, learned how the operations worked, and handled tasks that many former executives might consider beneath them.

That hands-on approach helped him understand the business from the ground up. It also made the company less fragile. In a large organization, one person leaving rarely threatens the entire business. In a small company, losing the only person who understands a key process can create serious problems.

For new entrepreneurs: learn enough to understand the work before you pass it to someone else.

Passion for the craft is not enough

Near the end of the interview, Rosenthal shared one of the most important lessons for anyone starting a business.

Being good at something is not the same as being ready to run a business around it.

A person may be great at baking cakes, designing websites, fixing cars, or coaching clients. But entrepreneurship also requires a passion for business itself. Sales, operations, hiring, cash flow, customer service, and risk all show up quickly.

An entrepreneurial mindset means caring about the business side, not just the service or product. It also means finding examples of people who have done it before. Rosenthal noted that many people give up before they begin because they have never seen someone like them take the leap and succeed.

Seeing real founder stories matters. They make the path feel possible.

The real lesson in how to become an entrepreneur

Jared Rosenthal's story is not a simple success story about a viral truck. It is a leadership story about ownership, risk, humility, persistence, and smart adaptation.

He left behind corporate credibility and started with something simple. He learned the work. He changed the model. He tested bold business ideas. He built a marketing strategy that caught attention. He trusted an idea that others doubted. He kept going when the path was uncertain.

For anyone asking how to become an entrepreneur, his journey offers a grounded answer.
