Common Financial Myths
In discussions about personal finance, "passive income" has become almost the ultimate goal. Social media is flooded with headlines like "Earn 100,000 yen a month in rent" and "Build financial freedom with online passive income," giving the illusion that if you find the right method, money will roll in automatically. What makes this narrative compelling is the idea that a shortcut might be possible — without having to significantly increase your primary income or strictly control expenses, you can simply copy a formula and skip the long process of building assets. However, if you look closely at those who have built long‑term financial security, you’ll see that their path is very different from this myth. They didn’t suddenly become wealthy from a single passive income source; instead, they constantly optimized their income structure and asset allocation over a long period of time.
The risk of this myth is that it turns "passive income" from a mere outcome into a goal. When the goal is set incorrectly, all effort loses direction. Researcher B. J. Novak writes in his work: the definition of "success" for most people is too narrow, focusing on a single metric and often ignoring the overall systemic nature. This view applies equally to personal finance — emphasizing only the numbers of passive "income" while neglecting the systematic foundation that must be built behind it.
Logical flaws behind
The first layer of gap in this myth is treating “passive” and “no initial investment required” as equivalent. In reality, true passive income sources that can generate stable cash flows—such as rent, royalties, dividends, or systematized online businesses—all require a substantial amount of upfront preparation. These preparations may involve capital outlays, the accumulation of time, or systems built through trial and error. More importantly, these inputs themselves are not “passive”; rather, they involve actively choosing to defer satisfaction and committing resources to long‑term value creation. The economic theory of “time preference” explains this phenomenon: individuals who are willing to sacrifice current consumption can obtain greater rewards in the future.
The second layer of the gap lies in overlooking the maintenance costs required for passive income. Rental apartments require management and repairs; dividend income changes with shifts in a company's health; online systems need continuous updates to respond to market fluctuations. All of these represent hidden costs of time and energy. When calculating “passive income potential”, many people only look at the revenue figures and fail to factor in the ongoing inputs required to sustain those income streams. This is akin to forgetting the large amount of actual labor that founders must invest during the system‑building stage when calculating the startup’s “passive income”. Research shows that about 70% of new ventures fail within the first five years, and one of the main reasons is that founders underestimate the ongoing maintenance costs needed to keep the system running.
How I actually think
In my view, passive income should not be the starting point of one's financial plan, but rather the end point. It is the result of systematic thinking and long‑term execution, not a shortcut. The core of this view is that what truly affects wealth is not which passive‑income tool you choose, but whether you have a complete cognitive framework regarding 'income structure' and 'asset allocation'. The mistake many people make in financial planning is not a lack of investment knowledge but a lack of framework. When they see an opportunity they jump at it, but they do not ask themselves how this decision aligns with their overall financial logic.
In practice, I tend to focus on two quantifiable metrics—'cash‑flow management' and 'asset accumulation rate'—rather than the vague vision of 'passive income'. If your cash‑flow inflows and outflows have a clear structure and your asset allocation aligns with your risk tolerance and time horizon, passive income will naturally become part of the overall system. Conversely, if you skip these foundational steps and directly pursue passive income, you often fall into one of two traps. These are either investing in the wrong assets and incurring excessive risk, or building a passive‑income source that requires heavy maintenance, turning it into another form of 'active work'.
Direction for building the correct framework
The first step in building the correct financial framework is to clarify the concept of “income layers.” Starting from the most basic “active income” (main‑job salary, freelance), moving through the transitional “semi‑active income” (side‑job that invests some time), and finally reaching “passive income” (cash flow that requires almost no ongoing maintenance after systematization), this is a step‑by‑step process. Each layer has its own function. Active income provides a stable cash foundation, semi‑active income tests the market and builds a prototype system, and passive income is the leveraged result of early‑stage investments. Jumping directly to pursue passive income often leads to a financial crisis during the system‑building stage because the cash‑flow foundation is insufficient.
The second step is to set criteria for “asset screening.” Not every cash‑flow‑generating asset is suitable for you. A truly worthwhile passive‑income tool must meet several conditions: it matches your risk tolerance, it aligns with your time horizon, its maintenance cost is sustainable, and it is supported by long‑term structural demand. For example, real‑estate rent in regions with a stable population structure has a long‑term demand base, whereas in areas with oversupply or population decline, the same asset can be a drag on cash flow. When choosing, you should ask not “how much income can this tool generate” but “how sustainable is this system in the long run.”
The third step, and the most important one, is to understand the priority of "system versus income." Most people focus on "how much passive income they can generate," but what truly affects results is whether the system you have built can withstand the test of time and the market. A complete system self-reinforces over time — income brings capital, capital optimizes the system, and the system generates further income. This is not a one‑time event but a positive loop. Shifting the focus from high income numbers to the quality of the system makes the logic of the entire plan clear. Prioritize the framework first, tools second — this is the final and most important puzzle piece in your personal financial plan.
The author of "Financial Freedom Practice Guide," Baton Copeland, once pointed out: "Money itself is not the goal; the goal is the freedom of choice that money can provide." True passive income is not the number in your account, but whether you have a system and knowledge sufficient to sustain that number. If the framework is correct, the puzzle pieces will naturally fall into place one by one.
