Most people don’t have a spending problem. They have a system problem:

• They earn money.
• They spend money.
• They vaguely hope things will work out.

Ten years later: “Wait… where did my money go?”

This is especially true for many smart, successful women I know, not because they’re less capable, but because no one ever gave them a clear, simple playbook.

So here it is.

Step 1: Understand Your Cash Flow.

Let’s make it real.

Case A: $100K income

• Gross: $100,000
• Taxes (~30%): $30,000
• Net: $70,000 (~$5,800/month)

Spending:

• Rent: $2,200
• Lifestyle: $3,000
• Total: ~$5,200

Savings: ~$600/month (~$7,200/year)

You’ll be fine. You won’t be rich.

Case B: $150K income (same lifestyle)

• Net: ~$105,000 (~$8,750/month)
• Spending unchanged: ~$5,200

Savings: ~$3,500/month (~$42,000/year)

Now we’re talking. Wealth is built by savings rate, not investment brilliance.

• $7K/year → slow progress.
• $20K/year → real wealth.
• $30K–$40K/year → financial independence trajectory.

Step 2: Build Your Foundation.

1. Emergency Fund.

Keep: 4–6 months of expenses in cash.

Example: $5K/month spend → $20K–$30K reserve.

This is not for returns. This is for not making stupid decisions under stress.

Put it in a high-yield account like the Wealthfront Cash Account which currently earns 3.30%.

Why I like Wealthfront Cash:

• Very easy UX.
• Easy online setup.
• Good yield.
• No minimums / no monthly fees.
• Strong liquidity features.
• Strong FDIC coverage structure through partner banks, with eligibility up to $8 million for individual accounts

Keep your emergency fund and short-term cash here.

2. Kill Bad Debt.

Credit cards = guaranteed negative returns.

Pay them off!

Step 3: Where to Invest (The Only Order That Matters).

This is where most people get it wrong.

1. 401(k) → Up to Employer Match.

Take the free money. If your employer matches, take it. Always. No exceptions.

Example:

• You put $5K
• Employer adds $5K
  → Instant 100% return

2. Roth IRA → Max It.

If there is no match, this becomes your first priority.

• You contribute after-tax money.
• It grows tax-free forever.
• You can withdraw contributions anytime.
• Full investment control.

This is underrated because it’s both a retirement account and a flexibility tool. For most people in their 20s and 30s, especially those not yet at peak income, this is usually better than a 401(k) without a match.

2026 limit: $7,500/year.

3. Taxable Brokerage.

This is where most advice gets lazy.

You’ll often hear: “Max your 401(k) before anything else.”

A 401(k) is often more tax-efficient because it avoids tax drag during compounding. However, withdrawals are taxed as ordinary income, while taxable investments benefit from lower capital gains rates and full flexibility.

In addition to saving for the future, you can use your taxable brokerage for:

• Quitting your job.
• Traveling.
• Starting a company.
• Leaving a bad relationship.

That’s why on average I would say only do the 401(k) up to the employer match, then max the Roth IRA, then go taxable. You don’t want to end up retirement-rich but life-poor.

That said if you have very high savings, are in a high tax bracket, are stable in your career and location, and don’t need near term liquidity, you can also contribute to your 401(k) beyond the match for up to $24,500 per year total.

Step 4: What to Actually Buy.

Don’t overthink this.

Option 1 (Best for 90% of people)

• 100% VT (global stock ETF)

Done.

Note that most 401(k) plans don’t offer global ETFs like VT. In that case, just use a low-cost US equity index fund (like an S&P 500 fund) inside the 401(k). Then use VT in your Roth IRA and taxable account. Because VT is ~60–65% US, this naturally brings your total portfolio to roughly 75–80% US / 20–25% international, which is exactly where you want to be.

Option 2 (Slightly optimized)

• 80% VTI (US)
• 20% VXUS (international)

Simple and effective if your 401(k) supports it. Replicate in your Roth IRA & taxable brokerage accounts.

What NOT to do:

• Pick stocks.
• Chase trends.
• Buy crypto as your core strategy.
• Build complex portfolios.
• Try to be clever.

That’s how people underperform while feeling sophisticated.

Step 5: Automate Everything.

Set:

• Monthly transfers.
• Automatic investments.

Then stop touching it. This is a system, not a hobby.

BTW I would have both the Roth IRA and taxable brokerage at Fidelity.

• Smooth app with the easiest UX.
• $0 commission for online US stock and ETF trades in retail accounts.
• Supports fractional shares of US stocks and ETFs.
• Has recurring investments for stocks and ETFs, with recurring transfers from $1 to $100,000.

Step 6: How You Actually Reach $1M.

If you invest $20K/year for 15–17 years at ~7–8% returns you end up around $600K–$1M+.

If you push that to $30K/year, $1M becomes quasi automatic.

No magic. Just consistency.

Bonus: Gifts & Family Money

This is wildly misunderstood.

In the U.S.:

If you receive money from a non-U.S. person:

• No tax!
• If > $100K → file Form 3520.

That’s it!

In France (important for many of my readers):

From parent → child:

• ~€100K tax-free.
• Per parent.
• Every 15 years.

So, a French parent can give €100K to each child, tax-free, every 15 years

Just:

• Declare it properly.
• Make sure it’s a real gift.

Bonus: Why Not Just Buy Real Estate?

Everyone says: “Real estate is the best investment”

It can be, but it’s often misunderstood.

The upside:

• Leverage.
• Potential appreciation.
• Rental income.

What people ignore:

1. It’s not passive.

You’re dealing with:

• Tenants.
• Repairs.
• Management.
• Vacancies.

Airbnb? That’s a job!

2. It’s a capital sink.

You pay:

• Maintenance.
• Repairs.
• Property taxes.
• Insurance.

As a homeowner, I can tell you things break constantly.

3. It’s illiquid.

You can’t sell 5% of your apartment. You can with ETFs. Moreover, it can take a long time to sell. My apartment has been on the market for over a year. You can sell the ETF essentially instantaneously.

4. You’re concentrated.

• One property
• One location
• One market

That’s risk.

5. The math is often bad right now.

I wrote a blog post in 2006 explaining why it made more sense to rent in what I perceived to be a real estate bubble: Rent… unless you want to buy. In it I explain the economics of real estate ownership. The same arguments are true today.

At today’s high prices and high mortgage rates, especially in places like New York, rental yields are often extremely low.

If I were to rent my apartments out, the rental income would not cover mortgage + property tax + maintenance + repairs. Real yields are at best 2-4% not including your time and more typically negative these days.

The only thing that can make the math work is appreciation. However, you’re taking leverage risk, on a single illiquid asset, hoping prices go up. Prices don’t always go up. I am selling my NY apartment for much less than it cost me, and I bought it 10 years ago!

Most people buying real estate today are not buying an investment. They are buying a leveraged bet on appreciation with significant operational complexity.

Compare that to ETFs:

• ~7–8% long-term returns.
• Fully liquid.
• Globally diversified.
• Zero operational overhead.

Do you really want complexity + leverage + risk for 2–4% (at best) over simplicity + liquidity for 7–8%?

Real estate works if:

• You love it.
• You operate at scale.
• You’re good at it.

For most people index investing is easier, safer, and more scalable.

Final Truth

You don’t need perfect timing, complex strategies, financial genius.

You need to save consistently, invest simply, avoid doing something stupid.

If you do nothing else do this:

• Build a 4-6 months emergency fund (Wealthfront Cash).
• Take your 401(k) match.
• Max your Roth IRA in VT (Fidelity).
• Invest the rest in VT in a taxable account (Fidelity).
• Automate everything.

Then go live your life. Wealth is not built by obsessing over money. It’s built by setting the system once… and letting it run for 15 years!

Most people don’t fail because they picked the wrong ETF. They fail because they never built a system and stuck to it.
