"多く稼ぐためには多く使わなければなりません"

Simplified Meaning:

To make a significant amount of money, you often need to invest a lot of money first. Think of a farmer who wants a big harvest. He has to buy good seeds, fertilizer, and proper equipment. Without those investments, his crops might not grow well, and he won't have much to sell. In business, this idea is the same. If someone wants to start a successful company, they might need to spend money on things like a good location, talented employees, or quality materials. Sure, it might feel risky to spend that money upfront, but it can lead to better results and bigger profits in the future. A historical example is Thomas Edison, who spent a lot of time and resources experimenting before inventing the electric light bulb. Without his investment in trials and errors, we might not have the convenient lighting we enjoy today. So, if someone wants great rewards, they should be prepared to invest in their idea or project.
