Investing

Rule number one, never lose money. Rule number two, never forget rule number one.

Invert the question. Ask what guarantees ruin: betting money you can't survive losing on something outside your circle of…

Wrong question. The right one is, how do I know I'm right? Find the three most believable people who think your idea is bad and…

Deflated? Over a week? Somebody out there is working twenty-four hours a day to take your market while your team feels sorry for…

Let us be precise about terms. Staking savings you need on a single unproven venture is speculation, not investment, and there is…

Never speculate with money you need; that rule has no exceptions.

Look, I bet big my whole life, but here's the rule I never broke.

Wrong question. First, do you have a measurable edge, or just enthusiasm?

The relentless rules of humble arithmetic apply to careers too.

I borrowed ten thousand dollars in 1939 to buy every stock under a dollar while the world marched to war, so I will not counsel…

Can you tell me the story in two minutes, in crayon? Not the dream, the story: who buys it, why they come back, how the earnings…

Wrong question. First tell me how much you can lose and whether you can live with it, because I never ask about upside until I've…

The whole game is preservation of capital and home runs. If you have real conviction, meaning you've done the work and see what…

The question isn't safe versus bold, it's what's the asymmetry.

Stop the madness. Your money is your soldiers, and you're asking permission to send them on a suicide mission.

Honey, I built my whole company on a thousand-dollar loan and an insult, so I'm biased.

I'd frame it as position sizing rather than a binary. Your savings are your liquidity buffer, and running that to zero is how…

Neither, until you value it. Write the story first: who pays you, why they pick you, what kills it.

Read everything first. Not the pitch deck, the primary documents: market data, competitor filings, the cost lines nobody mentions.

Wrong question. The Patels did not ask safe or bold when they bought motels with everything they had.

Cold read first, no story. Write down what the idea costs to test, what it earns if it works, and what you have left if it fails.

Give me the five-year view of your idea, not the five-week one.

Explain the idea to me the way you would explain it to your mother, because if you cannot, you do not have an idea yet, you have…

First question, always: what does it cost? Not the dream, the idea.

Alright, let's do the math out loud. The answer is never all-or-nothing, it's the gap.
