Editor’s Note: Over the next seven days, we’ll feature the greatest wealth-building insights of all time. We’ve dubbed it “Wealth Week 2015.” As you’ll see, these fly in the face of what Wall Street presents as the path to building wealth… which is a good indicator of their genuine usefulness…

Mark Ford

From Mark Ford, founder, Palm Beach Research Group: I consider myself an expert of sorts on retirement. Not because I’ve studied the subject, but because I’ve retired three times.

Yes, I’m a three-time failure at retiring. But I’ve learned from my mistakes.

And I can tell you the biggest mistake retirees make is giving up all their active income.

By active income, I mean money you make through your labor or through a business you own. Passive income, on the other hand, is what you get from Social Security, a pension, or a retirement account.

It’s a very common mistake. Yet I’ve never heard retirement experts mention it. Nor have I read a word about it in retirement books.

When you give up your active income, two bad things happen:

  1. You cut your connection to the source of that income. I’m not just talking about the business you had or worked for, but also about the people you knew. (These are valuable connections you might want to revisit someday. But with every passing month, it’ll become more difficult.)
  2. You debilitate your ability to make smart investment decisions because you’re now dependent on passive income. (I’ll explain this later.)

  Funding the “dream” of retirement

Here’s how retirement is supposed to work: You save a portion of your income every month, let it grow in a tax-deferred investment vehicle, and accumulate a vault of wealth.

Then, 40 years later, you tap into that vault to fund 20 years of easy living. No work. No stress. Nobody to kowtow to.

Just traveling, golfing, going to the movies, and visiting your kids and grandkids.

Yes, it’s a great idea. But it was never realistic.

Prior to the 20th century, retirement was a rarity. Most people worked until they could no longer work, then “retired” into their children’s homes.

The only generation that experienced “the dream” was my parents’ generation—the men and women who bought starter homes and entered the workforce after World War II. They had good timing, because the U.S. was entering a 30-year growth spurt in business and real estate.

They made and saved money, but the bulk of their retirement funds came from selling their homes in 1980 for 10 times what they’d paid for them in 1950.

For every generation since then, the promise of that kind of retirement has been a big white lie.

Consider this: A “dream” retirement lifestyle for two would cost, on average, $75,000 per year (depending on where you live).

And that’s after-tax dollars.

If you were in the 32% bracket, you’d have to earn about $110,000 to end up with $75,000. So, let’s use this $110,000 figure.

How big of a retirement account do you need to produce $110,000 of cash flow each year?

Let’s assume you and your spouse could count on $25,000 per year from Social Security and another $25,000 from a pension plan (two big assumptions). To earn the $60,000 balance in the safest way possible (from a savings account), you’d need about $6 million. (Savings accounts pay—at best—only 1% right now.)

If you were willing to take more risk and invest in tax-free municipal bonds, you’d need $2.1 million.

But let’s say you were confident you could earn 8% from the stock market. You’d still need a nest egg of $750,000 to gross the extra $60,000 per year ($750,000 multiplied by 8%).

The problem: Most middle-class Americans are trying to retire with an account in the $250,000-300,000 range.

And that’s where the trouble begins. To achieve a return of $60,000 on $300,000, you’d need to earn 20% on your money. Getting (or attempting to get) 20% consistently over, say, 20 years is next to impossible—and too risky for my taste.

  A lesson learned from retirement No. 1

I retired for the first time when I was 39. I had a net worth of about $10 million, half of which was liquid. I thought I had all the money I’d ever need.

As it turned out, my retirement lifestyle was a lot more expensive than the $75,000 “dream” lifestyle I described earlier. I liked first-class travel, five-star hotels, and fancy cars. My yearly nut was close to $500,000.

To generate $500,000 in after-tax dollars, I would’ve had to earn $900,000 in passive-interest income on the $5 million I’d invested. That represents a return of 18%. I understood enough about stock market performance to know it was impossible.

I should’ve cut my expenses drastically. But I didn’t want to. I enjoyed my lifestyle. So, I had no choice. I had to go back to work.

I put the word out and got a few offers. A month later, I was back at work. I half-expected to feel miserable toiling away.

But the moment I started earning money again, I felt better.

  How retirement should feel

Retirement isn’t supposed to be about money worries. Yet, if you retire with too little, that’s exactly what you’ll have. Trying to get above-market returns is challenging under any circumstance. But when you have to get high returns to pay the bills, it can be extremely stressful.

As I write this, millions of Americans my age are quitting their jobs and selling their businesses. They’re reading financial magazines and subscribing to newsletters. They’re hoping to find a stock-selection system that’ll give them the 20-40% returns they need.

But they’ll find out such systems don’t exist. They may have a few good years, but eventually, the returns they get will drop to 10% or less… if they’re lucky.

And if there’s another stock market crash, things will get bad—fast.

But it doesn’t have to be this way.

Let’s go back to the hypothetical situation I laid out earlier. You have a $300,000 retirement fund and a retirement dream that’ll cost $75,000 in after-tax dollars.

To end up with $75,000 in after-tax dollars, you need an income of $110,000. You and your spouse have a total of $50,000 per year coming from Social Security and pension payments. But you still need $60,000 per year in pretax passive income.

To earn $60,000 on $300,000, you need a return of about 20%. That’s highly improbable. But if you and your spouse both got part-time jobs that gave you an extra $15,000 per year in active income ($7,500 each), you’d need a return of only about 8% on your retirement account. And that’s very doable.

I’m not saying you should give up on the idea of retirement. I’m saying you should think of retirement differently. Instead of spending 80% of your time working for money and 20% having fun, you can spend 20% of your time working and 80% having fun—and be free from financial worries.

That doesn’t seem so bad, does it?

And if you’re smart about the kind of work you do, you can actually have fun working!

There are many ways for a retired person to earn a part-time, active income. You could do some consulting, start your own online business, or earn money doing any sort of purposeful work.

Another option—and a great one, if I do say so myself—is to consider joining the Palm Beach Wealth Builders Club, the private coaching group I started with the very intent of helping you quickly create additional streams of passive and active income. It’s intended for folks who have fewer than seven years until retirement but are coming up short on funds.

As an example, for the WBC, I wrote a series of essays we call the Extra Income Project. In these essays, I provide you with my favorite extra-income opportunities. I wrote the first 12. Then, Bob Bly, a mastermind at small-business ideas, wrote dozens more—with others still to follow.

Often, these essays come with companion reports and manuals that explain what you need to do to initiate any of these extra-income streams. I also recommend accompanying programs that tie into each opportunity. If an essay doesn’t have an accompanying report, we’ll suggest books or relevant websites for you to consult.

Each and every one of these essays is dedicated to helping you increase your income. They range from things you can do immediately (such as learning how to get your boss to give you a big raise) to longer-term projects (like converting the skills and knowledge you already possess into cash).

Here are a few examples:

  • How my friend accidentally made $1 million using the “Wal-Mart strategy”
  • The secret to turning your favorite hobby into an extra $4,000 per month
  • How my golf buddies make $75,000 per year in rental real estate without investing a nickel
  • Know something about anything? How to earn $9,800 by talking about it
  • How to fill your wallet by emptying your junky attic
  • How to actually achieve what 82% of Americans only dream about: becoming an author
  • These companies are hiring: $60,000 for two hours per day
  • Steps for profiting off your vacation photos
  • Ways to earn $50-500 per hour in this virtual marketplace
  • How to earn six figures telling others what to do
  • Dr. Rankin: “How I quit my practice, started a blog, and doubled my salary.”

Adjusting your understanding of “retirement” to include some active income isn’t a huge burden. You can end up doing a lot of the same things you envisioned before—but get paid for it instead of doing it for free.

So please, move beyond the big white lie of investing. A rewarding and enjoyable retirement—devoid of money worries—awaits.
