Serial entrepreneurs don't just jump into new fields. There are basic strategies they typically employ. They focus on businesses that are close together because the ecosystem is stronger, branding is easier, and distribution can be shared. Leveraging the same resources (raw materials, team, channels, machinery, or network). Following market demand. Serial entrepreneurs also sometimes enter different industries so that if one sector declines, others can continue to thrive.
Successful serial entrepreneurs always think like this: Don't just sell products, but build a business engine. That engine can be replicated in various new products/businesses. The result: instead of having multiple, disorganized businesses, they have a mutually reinforcing business ecosystem.
Essentially a serial entrepreneur is someone who simultaneously runs several businesses throughout their career, and it's not limited to just one or two businesses. However, referring to the capabilities of most people, perhaps not all of them can run simultaneously due to certain limitations. Those with more forward-thinking abilities will always make innovations to their businesses in a more coordinated way over the long term so that their progress can be mutually reinforcing.
Not many people can truly achieve the true meaning of serial entrepreneurship because as I mentioned earlier, there are limitations. Therefore, it's better to focus on a business you're more adept at managing, which will significantly increase your potential for success, rather than being greedy and overextending yourself be in serial entrepreneurship.
