With equity markets hovering near all-time highs, the lessons in Morgan Housel's The Psychology of Money are worth revisiting.

‍

Through the lens of a credit investor, three ideas stand out:

‍

1) "Things that have never happened before happen all the time." — Stanford professor Scott Sagan. Markets are probabilistic: a good decision can produce a bad outcome, and a bad decision can produce a good one. A conservative lender looks boring until the cycle turns, which is why managers should be judged on process, not short-term performance.

‍

2) Building wealth and keeping it require different mindsets. Building wealth typically requires optimism and risk-taking (or a trust fund). Keeping it requires restraint and respect for uncertainty.

‍

3) The goal is not to maximise returns; it is to avoid fatal mistakes. Compounding is the most powerful force in investing, and its enemy is interruption. A strategy that delivers outsized returns most years but carries a small chance of wipeout is inferior to one that survives across cycles. Buffett puts it best: "Rule No. 1: Never lose money. Rule No. 2: Never forget Rule No. 1."

‍

These principles are the foundation of sound credit investing. The job isn't to shoot the lights out in a single quarter, it's to avoid the mistake that permanently impairs capital. Once capital is gone, optionality is gone with it. The goal is to stay solvent, adaptable, and compounding long enough for time to do the heavy lifting.

‍

The best credit managers embed this ethos into their process, treating strong collateral, protective covenants, and downside protection as core features of the strategy.

‍

As I often say: "Optimists make terrible credit investors." That's why the best credit managers sound less like traders and more like capital stewards. They care about downside first, because the upside in credit is usually bounded while the downside can be open-ended if the structure is wrong. In that sense, Housel's survival principle isn't just compatible with credit investing, it's the foundation of it.
