Michael Burry built his reputation on seeing a collapse before anyone else did, famously betting against the subprime mortgage market ahead of the 2008 financial crisis, a call later dramatized in the film The Big Short. Nearly two decades on, he is still skeptical of consensus optimism, recently suggesting the current enthusiasm around artificial intelligence amounts to a bubble that may burst sooner or later. But his latest widely discussed commentary is not about markets at all. It is a short list of personal advice, written on his Substack newsletter Cassandra Unchained, addressed to a 26-year-old reader asking how to think about life and money.
The housing advice, in his own framing
The advice that has traveled furthest is also the most concrete: buy half the house you can afford. The logic is not about frugality for its own sake, it is about avoiding the trap of a mortgage payment large enough that it effectively chooses your career for you, locking someone into a job they would otherwise leave simply because the monthly bill demands it. He extends the same caution to other big-ticket purchases, suggesting that anything that flies or floats, meaning planes and boats, is usually better rented than owned.
A wider philosophy about avoiding being boxed in
The rest of the list reads less like a financial plan and more like a set of guardrails against the kinds of decisions that quietly narrow someone's options later in life. He advises against gambling entirely, and argues that genuine enjoyment rarely requires expensive purchases, since appreciation itself, in his phrasing, is cheap. Alongside the money-specific points, he urges continued physical exercise and lifelong learning, a willingness to compromise early in relationships rather than waiting for a perfect match, and an appreciation for how compounding, whether of money, habits or relationships, rewards patience over time. He also lists having and raising children well, and practicing charity and gratitude, among the habits he considers worth building deliberately.
