The phrase "passive income" has been so thoroughly colonized by people selling courses about passive income that it's become almost meaningless. I want to reclaim a useful version of it — or at least give you my working definition, which I think is more honest than the way the term usually gets used.
But to get there, I need to walk through the full spectrum of how income actually works. Because the interesting territory for our purposes isn't at the extremes — it's in the middle.
Active income: you trade time for money.
This is where most people live. You work, you get paid. The ratio of pay to time can vary enormously — a lawyer billing $800 an hour is still trading time for money, same as someone earning minimum wage. The ceiling is real: there are only so many hours in a day, and when you stop working, the income stops.
Active income has a lot to recommend it. It's predictable, it's responsive to your effort, and it compounds in ways that get underappreciated — the skills you develop doing active work increase your value over time. I spent fifteen years doing active-income work and I'm not going to pretend it was worthless. The legal career built skills I use every day in this operation.
The limitation is that it doesn't scale. If you're building for leverage — for the ability to earn more than you can personally produce in hours — active income is the starting point, not the destination.
Truly passive income: the asset earns, you sleep.
The idealized version: you own a thing, the thing earns money, you do nothing. Index funds come closest to this in practice. Real estate can approximate it if you have a good property manager. Royalties from a book or patent can, in a good year, be close to this.
But truly passive income is rarer and harder to build than the genre suggests. Most of what gets sold under the "passive income" label has an active income component that's been deliberately obscured — the YouTube channel that "runs itself" still requires someone to maintain it, the rental property still requires management, the affiliate blog still needs someone to update the content when Google changes the rules.
I'm not criticizing. I'm just saying: the truly passive end of the spectrum is a destination, not a starting point, and the journey from here to there usually involves a lot more active work than the marketing suggests.
Near-passive income: where the interesting territory is.
Between "you stop working, the income stops" and "you do nothing and the money arrives" is a range of structures where the work is front-loaded and the returns are back-loaded. Where you build something, and that something continues to earn in some proportion to its accumulated value rather than your current labor.
A newsletter with sponsors and paid subscriptions. An SEO-optimized website with affiliate revenue. A book that keeps selling because the work of writing it is done. A product catalog in a print-on-demand store. A mobile app that charges subscriptions.
In each of these, there is real ongoing work — maintenance, updates, community management, fresh content, customer service. I don't want to minimize that. But the relationship between current labor and current income is different than in pure active income. You're earning partly on yesterday's work. That's the near-passive property.
Why this matters for portfolio design.
The ten-stream thesis is built specifically on near-passive income streams. If I were building a portfolio of active income streams — consulting, freelancing, agency work — diversification would actually work against me. Splitting your time between five active-income projects means you're doing all five at fifty percent capacity, which typically produces worse outcomes than doing two well.
But near-passive streams have a different marginal cost structure. Once a directory is built and ranking, maintaining it doesn't require your full attention. Once a product catalog is established in a POD store, monitoring its performance is a small fraction of the time that building it required. Once a newsletter has a publishing rhythm, each issue is a smaller increment than the first hundred.
This is why ten is plausible. Not ten things demanding your full attention simultaneously — that would be chaos. Ten things, each of which required a heavy front-loaded investment, that now hum along at a fraction of their initial maintenance cost.
The compounding logic: each stream's maintenance demand decreases over time (in theory), which creates capacity for the next stream. You're not dividing your attention — you're expanding your portfolio as the earlier investments mature.
The honest caveat: this is the plan. The plan has not yet been validated by three to five years of actual execution. We are in the front-loading phase right now, and it doesn't feel especially near-passive at the moment. Ask me again in two years.
This Week in AI: The question of whether AI will replace knowledge workers has been debated extensively, and the honest answer seems to be: it depends heavily on which part of the knowledge work you're looking at. The research and production tasks are getting automated. The judgment, relationship, and context tasks are not — or at least not at a pace that makes them irrelevant to plan around. For builders, this argues for leaning hard into judgment and strategy while offloading production aggressively.
