One difference I see between a businessman and an entrepreneur is diversification. A businessman might just focus on his business, ensuring it's working well and managing it properly. He might not necessarily introduce new things. For example, if he's  selling car parts, he might have different types of car parts, making the car parts store bigger and managing it.

On the other hand, an entrepreneur can diversify. They see opportunities in everything. An entrepreneur can start by selling car parts, then gradually introduce services like fixing car parts, home delivery of car assesories, and other related services. From one business, they can create multiple related businesses.

That's how I see an entrepreneur, they diversify a lot and tend to see opportunities where others see problems. Even during a lockdown, entrepreneurs can find ways to work. Instead of sitting idle, they think of something, offering their services from indoors.

Entrepreneurs have the ability to multitask, be proactive and have two, three, or four related businesses, rather than just focusing on one and managing it. That's one difference I see.
