Metropolis and Transportation: For mankind, a ‘city’ was a ‘place’ where people were born, grew up, and eventually died. It was initially difficult for humans to choose a ‘place’ to live. Humans had to follow the fate they were given. However, with the development of transportation and the widespread adoption of online networks, humans have been able to select their own places of residence. Throughout history, humans have only been able to voluntarily choose where they want to live for a short time. Achieving freedom of movement marks a fundamental change in the form and character of cities. The development of transportation has completely transformed our lives. The emergence and evolution of transportation means, such as electric vehicles and high-speed trains, indicate that we are in the middle of a revolution that humanity is experiencing for the first time. If you do not respond to these changes, you will face difficulties. - Joseph’s “just my thoughts”
In business, capital means business funds. A successful entrepreneur often says, "I started my business without any capital". It's partly true, but it's a lie. The entrepreneur just said that capital means only cash. However, all kinds of businesses need to be fundamentally business funds in any even not cash. The entrepreneur didn't count the founder's labor cost. No inputs, no outcomes. The uncounted labor costs are called "alternative costs" or "opportunity costs". This comes from comparative advantage. If the entrepreneur doesn't accept the uncounted labor cost as a debt, the entrepreneur is equivalent to losing the profit due to opportunity costs. Please always remember this. There is no free lunch in this world. - Joseph’s “just my thoughts”
