FRUGALITY

Stop trying to cut lattes. Start trying to earn more. The upside on income is unlimited. The upside on frugality is capped at what you already spend.

I was making $100,000 a year and spending $50 a month on food. Not because I had to. Because every dollar I didn't spend was a dollar that could make me more money.

Wealth is what you don't see. It's the cars not purchased. The diamonds not bought. The renovations postponed.

I wear the same polo shirt every day. I have no interest in looking rich. I have interest in being right about where to deploy $900 billion.

I still fly economy class. Saving money is not about poverty — it's about discipline.

I fly economy sometimes. People think that's weird for a billionaire. I think it's weird to pay ten times more for the same destination.

Our robots cost $2,500 to build. Competitors spend $40,000. We deploy five robots for the price of one.

We built our first robots in Colombia because Silicon Valley's cost structure would have killed us before we started.

I am not a hard woman. I simply know the value of a dollar.

I'm not the Rockefeller type. You can only wear one pair of shoes at a time.

Money looks better in the bank than on your feet.
