I have a confession to make: I am not a wealthy man. Now, this information might be worrisome to some of you in light of the fact that I work for a company that provides advice on how to maximize personal wealth. I do, however, have a good explanation for my relatively modest financial situation.

I spent most of my 20s without an income, languishing away in grad school. During my 30s, I earned a pittance teaching history to college students. Only recently did I leave academia for the private sector, motivated by such grandiose dreams as being able to afford my own home and send my kids to college. All things considered, I have only one major regret over the past 20 years or so: I didn't invest early enough in the great companies of our generation. Where was the Motley Fool Rule Breakers service when I was 21?

What's past is prologue
During the past 20 years, the American economy has experienced phenomenal growth, fueled by a technological revolution that has transformed the way we work, shop, and communicate.

From 1984 to 2003, GDP grew by 77%, and manufacturing productivity expanded by more than 100%. To see how far we've come, just have a look at an old Star Trek episode. What was supposed to look futuristic back in the 1960s now looks utterly ridiculous. My underpowered laptop appears far more useful than anything Captain Kirk had at his disposal to navigate the USS Enterprise.

During the 1980s, developments in the computer industry provided a much-needed stimulus to a U.S. economy still smarting from the stagflation years of the previous decade. Innovative companies such as Intel (NASDAQ:INTC), Infosys (NASDAQ:INFY), and Dell led the way in this sector. In the 1990s, visionary enterprises such as Amazon.com (NASDAQ:AMZN) and eBay (NASDAQ:EBAY) ushered in the Internet era. Entrepreneurship was not, however, limited to computer firms and Internet companies. Dynamic retailers such as Lowe's (NYSE:LOW) responded to new economic trends and began selling familiar products in more profitable ways. In the sciences, biotech firms like Amgen (NASDAQ:AMGN) and Genentech (NYSE:DNA) emerged with breathtaking discoveries in the realm of cellular and molecular biology.

All eight of the companies mentioned above broke the rules when they first appeared on the scene. Indeed, David Gardner, lead analyst for Rule Breakers, started touting each of these companies from the early 1990s onward. Now, of course, long after the fact, conventional wisdom recognizes the genius of these companies. And four of the eight are now considered among the 80 most respected companies worldwide, according to a recent survey by PricewaterhouseCoopers.

So imagine what would have happened if I had plunked down $1,000 on each of these outstanding firms early on in their high-growth stages?

What's interesting is that since this article first ran, Dell has been pummeled by the market. Even after declining from a 40,000% return, it's still up 31,000% for early investors! A paltry $1,000 investment in Dell back in 1988 would have yielded $307,750 today. With that kind of performance, I suspect I'd now be in a position to purchase my own home, which would be a big improvement on the substandard dwelling I'm currently renting. On a less spectacular scale, $1,000 invested a mere nine years ago in Amazon.com would have grown to $25,500 by July 2006. That figure approaches a year of tuition (excluding fees) at Harvard. And I would still have 10 more years to invest for the other three years of college, as my oldest is only in second grade.

Wait just a minute ...
Now, some of you might object. Surely, it is not very likely that an investor would have been able to get in on the ground floor of all of these great companies. Perhaps you are right. Let's see what would happen if we delayed our investments in three of the above companies by two years, which might have given us more time to monitor these high-growth businesses.

My hypothetical return in Dell would have remained exactly the same, while my returns in Amgen and Intel would have declined considerably by waiting -- not that I'd complain about those returns. So we see that the great companies are still available at reasonable valuations early in their growth stages. You don't have to sniff out Starbucks at its first coffee bean to turn a very nice profit.

Money for nothing ...
You might be thinking: I like those 31,000% returns; how do I get some of those? OK, now for some reality. The purpose of looking at the returns of the great companies listed above is not to show that growth investing is an all-win situation. Far from it. The purpose of the illustration is to demonstrate how well great companies perform over a long period. If you can identify just one great company early, and then hold on for the long term, you can do pretty well for yourself.

Growth investing is highly volatile and will fray the nerves of those individuals with a low risk tolerance. That said, all investors should devote a portion of their portfolios to growth stocks. For those traveling in the fast lane (has David Gardner really been ticketed for speeding 26 times?), an allocation of 30% of their portfolios might make sense. More conservative types should allocate at least 5% in order to provide a little juice for their investments. I'm somewhere in between, so I devote about 15% of my portfolio to growth. I'm looking to buy some of our Rule Breakers stock selections myself; in fact, I've purchased two of Charly Travers' biotech selections, one of which is up more than 200%.

Willie Sutton and investing
Should I concentrate all of my growth allocation on computer and Internet stocks? No doubt, there are still great opportunities in these areas. In fact, there's a Rule Breakers selection I like that utilizes the Internet in an entirely creative way to deliver one of the most timeless products out there. But we also need to find new areas to trawl for great companies.

You might recall the familiar story about Willie Sutton. When asked why he robbed banks, old Willie replied "because that's where the money is." With Willie's advice in mind, the Rule Breakers service focuses on those sectors where the next great companies are likely to emerge.

We now have expert analysts for the realms of biotechnology and nanotechnology. Meanwhile, David Gardner -- who as co-founder of The Motley Fool knows a thing or two about managing an innovative company that defies conventional wisdom -- leads the mission to size up which managers have what it takes to be called Rule Breakers. By joining that mission, you will essentially be hiring six dedicated analysts, each of whom has a track record of discovering great companies before the masses have even heard of them. You wouldn't climb Mount Everest without experienced guides, and you shouldn't pursue a growth strategy without excellent advice.

Epiphany
The high-growth train of the 1980s and 1990s has already left the station, and some of us were left behind, muttering obscenities to ourselves on the platform. We have two choices facing us today in 2006. One option is to lament our bad fortune, admit that high-growth stocks demand too much hard work and more than a bit of luck, and then resign ourselves to index funds, hoping to eke out 7% per year over the next 20 years. The other option demands boldness and vision. It asks you to forget the past and plan for the future by joining in the search for the great companies of the next 20 years.

The novelist George Eliot once said that "it is never too late to become what you might have been." That quote inspires me to seek those investments in the future that I didn't in the past. If you think our dedicated Rule Breakers team can help you in a similar quest, why not try a risk-free trial for 30 days?
