Thankfully, Getting Rich Is This Simple
Summarised with Bite · 12 min read
A former investment banker breaks down the six rules every wealthy person follows monthly, starting with a simple truth: your salary is just the starting point. What actually builds wealth is the gap between what you earn and what you spend, and how you protect that gap as your income grows. Most people optimize income but let lifestyle creep erase the gains.

The Wealth Equation Nobody Taught You
After 9 years in investment banking, the speaker learned that wealth boils down to a single equation most people never see: earn it, keep it, grow it. The wealthy optimize for the last two, while most people spend their entire career chasing the first. The gap between what you earn and what you spend is the only number that determines whether you get richer or stay stuck. Everything else, the job title, the bonus, the postcode, is just noise. In banking, the speaker watched colleagues earn massive salaries but maintain virtually no gap. The number on the payslip was huge. The number that mattered was zero. Here's the math that forces a re-evaluation: someone earning £80,000 who spends £70,000 saves £10,000 a year. Someone earning £40,000 who spends £25,000 saves £15,000. Three times more wealth on half the salary. The gap is everything. You can widen it two ways: earn more or spend less. Most advice starts with cutting back, but that's optimizing for the smaller lever.
