Jewish Wisdom on Money and Life, by Naftali Horowitz
Naftali Horowitz occupies a rare position: Senior Managing Director at JP Morgan Chase and a practising rabbi in New York. That dual lens — Wall Street rigour combined with ethical and spiritual grounding — makes him one of the most distinctive voices in personal finance today.
I first encountered him through the Kosher Money / Living L’chaim YouTube channel, where he shares timeless wisdom on money, character, and decision-making with a sharp and direct style that stays with you. What follows are six takeaways that have shaped my own thinking.
1. Debt: Live as if it doesn’t exist. Debt is more accessible today than ever, which is precisely why Horowitz urges treating it as if it barely exists. Good debt (a manageable mortgage, a business loan with clear repayment) is structured around assets and income. Bad debt — credit card spending on things you can’t afford today — is a trap. Credit cards should be a payment convenience, never a borrowing vehicle. Paying usury rates to a card issuer is one of the most expensive financial habits there is.
2. Discretionary spending: connect today’s ease with tomorrow’s cost. There are always cuts available in discretionary spending, but people avoid them because they never pause to link today’s convenience with tomorrow’s sleepless night. Tradeoffs exist at every income level — unless you are Jeff Bezos. Spending money you cannot afford to spend often starts as a habit, not a decision.
3. Financial education starts at home. If you send a child into adult life — or into marriage — without genuine financial education, you are simply deferring the problem. A spendthrift partner allowed to continue unchecked becomes a crisis that compounds over a decade. Parents who ignore this often end up picking up the pieces later, at far greater cost.
4. Investing: keep it simple and leave it alone. For the vast majority of people, investing does not need to be complex. Open a retirement account, buy a broad index fund like Vanguard Total Market, and let it compound. What Horowitz finds criminal is the opposite: people who leave their 401(k) sitting in cash for years, or a 26-year-old who picks bonds because they seem “safe.” At that age, the right strategy is growth and time — not stability.
5. Career first, side hustle second. Advancing in your primary career almost always generates better returns than diluting your energy across side ventures. The primary income comes from where you focus most. Investments and secondary income are tools for allocating the surplus — not for replacing what deep professional focus can build.
6. Real success is who you become. Net worth is a lagging indicator. Real success shows up ten years later: you manage time better, communicate more clearly, solve problems with more judgment, and act with stronger ethics. Success first. Wealth later.
