Escape Velocity
Personal expenditure < personal capital income.
That is the whole idea. On one side of that line you sell hours for money and the money is gone by the end of the month. On the other, what you own earns more than your life costs, and the arithmetic that held you down starts working the other way.
Most people never see the line, because nobody points at it. The number that gets tracked is net worth, which is a trophy rather than a threshold — it tells you nothing about whether you are free. The number that matters is a yield: does the capital cover the spending, with margin, in the currency you actually spend?
Four documents follow, and they answer different questions. The manifesto is the worldview — why the system runs this way and who profits from it. The investment thesis is the mechanics — every rule the portfolio obeys, written down before the fact so future-me cannot quietly rewrite history. The portfolio is the proof, kept in public. The calculator is the same arithmetic on your own numbers.
Read them in that order if you have an afternoon. If you have five minutes, run the calculator and see which year comes back. If you have two, read the essay — the whole idea in 499 words.
