Just Keep Buying: Proven Ways to Save Money and Build Your Wealth

Introduction

"The most consistent way to get rich is to grow your income and invest in income-producing assets. "Simple truth, but it contradicts most personal finance advice obsessing over lattes and budgets.

Maggiulli crunches historical market data to answer the biggest money questions: Should you buy the dip? Can you time the market? When should you sell? His findings destroy popular beliefs.

Even God couldn't beat dollar-cost averaging. Saving cash for market crashes underperforms just keep buying 70% of the time.

The book splits into two sections: how to save smarter as you grow wealthier, and why investing consistently beats trying to be clever.

This isn't about getting rich quick. It's about what actually works when you run the numbers across decades.

From Poor to Rich Mindset

Here's the uncomfortable truth about personal finance: what works when you're broke will sabotage you when you're wealthy. At 23, the author had $1,000 in his retirement account and spent hundreds of hours building Excel spreadsheets to optimize his portfolio allocation.

Should he put 15% in bonds or 20%? Meanwhile, he was dropping $100 on nights out in San Francisco without thinking twice.

The math exposes the absurdity. Even if he achieved a stellar 10% return on that $1,000, he would make $100 in an entire year.

He was casually spending that same amount in one night. Skipping a single night out would equal 12 months of excellent investment performance.

Now consider someone with $10 million invested. If their portfolio drops 10%, they lose $1 million.

Could they save a million dollars by cutting expenses? Unless they have an extraordinarily high income, not a chance. Their investment fluctuations dwarf anything they could possibly save.

This is why your financial strategy must flip as you build wealth. When you have little money, obsessing over investment allocation is pointless because the dollar impact is tiny. Your energy belongs on increasing income and savings. When you have substantial assets, investment decisions matter enormously because small percentage changes translate to massive dollar amounts.

The calculation is simple. Estimate how much you can comfortably save next year. Then calculate your expected investment growth in dollar terms.

If expected savings exceeds investment growth, focus on earning and saving more. If investment growth is higher, concentrate on portfolio optimization.

The transition happens faster than you think. Someone saving $10,000 annually at 5% returns starts with savings dominating their wealth building 20 to 1. After 30 years, their investment returns generate three times more wealth than their annual contributions. By the end of 40 years, nearly 70% of their total wealth comes from investment gains, not contributions.

Most financial advice ignores this shift and treats everyone the same. That's why people waste energy on the wrong priorities at every stage of their wealth building.

Review

So here's what the numbers actually say: grow your income relentlessly, invest what you save automatically, and ignore the noise. The math doesn't care about your feelings, and neither does compound growth.

Start with whatever matters right now—calculate that savings versus investment growth ratio, set up that 2x Rule for guilt-free spending, or just buy your first index fund tomorrow.

Because the biggest cost isn't what you lose in a crash. It's the decades you waste waiting for the perfect moment that never comes. Your future self is watching. Make them proud.
