Mental Models for Better
Financial Thinking

Every decision has a hidden cost — the value of the best option you gave up.

Break every problem down to its fundamental truths — then rebuild your thinking from scratch.

Ask not just "What happens next?" but "What happens after that?"

Always leave room for being wrong — that gap protects you when reality diverges from your plan.

Know exactly what you understand — and stay inside those boundaries when it matters most.

Think in probabilities and distributions — not certainties and predictions.

Instead of asking how to succeed, ask how to avoid failing — then avoid those things.

Every gain requires giving something up — understanding trade-offs is the basis of rational choice.

The investor who consistently asks "Where will this be in 10 years?" gains a massive advantage.

Preserve your right to change course — the ability to adapt is one of the most valuable assets you can own.

When choices are complex, score them systematically — the right decision becomes visible.

Every decision has a scoreboard — total the costs, total the benefits, and let the numbers guide you.

Treat easy-to-undo choices quickly — and treat permanent decisions with deep deliberation.

The most reliable way to avoid costly mistakes is to follow a pre-defined list before every decision.

See the whole machine, not just the part in front of you — because every component affects every other.

Find the point of maximum impact — where a small effort produces a disproportionately large result.

Understand how outcomes feed back into causes — and you will understand how wealth (and poverty) compounds.

80% of your results come from 20% of your actions — find those 20% and multiply them.

Compound interest is just the beginning — knowledge, habits, and relationships compound too.

Every decision has a hidden cost — the value of the best option you gave up.
