Study only businesses that one person can handle, because in today's environment, people are actually a liability. Ordinary people starting a business should never rush to hire. Many people think of entrepreneurship and their first instinct is: open a store, build a brand, stock inventory, hire a few people. Honestly, this logic might have worked 10 years ago. Anyone doing this now will fail. The biggest misconception for ordinary people starting a business is: thinking that hiring people = scaling up = making money.
