Where were you in August 1994, and what were you doing? When I tell you where I was, you won't believe it (of course, you have to read to the end to find out).

Were you at least buying stocks?
I wasn't. I sure wasn't gambling $1,800 on a company you'd never heard of. But somebody was, and he was about to make a lot of money. I know this for two reasons.

First, that one crazy trade made this guy a minor celebrity. Second, the crazy Fool shouted his intentions from the rooftops, before he went long, and then tracked his returns online for the world to see.

Five years later, the shares he bought for a split-adjusted $0.46 crested atop $50. Before you could say "Mad Money," Money.com called the guy "among the most widely followed stock market advisors in the world," and his $1,800 stake ballooned to $190,000.

Yes, you read that right
That stock was America Online -- and that guy was Motley Fool co-founder David Gardner. Granted, we were in a massive bull market, and that helps. But it doesn't explain everything. The fact is, David saw a first-mover in an emerging industry that was destined to change the way we live -- and had the guts to buy it.

Yes, the stock has been pounded since, but this may surprise you: David's AOL investment is still up. Way up. If you'd bought AOL with him, you'd be up 4,400%. If you caught a wave that was already building and bought another tech titan like Dell (NASDAQ:DELL) or even Apple (NASDAQ:AAPL) instead, you'd be up 5,574% or 1,363% respectively.

Even if you'd rolled the dice on old-school IBM (NYSE:IBM) or new kid on the block Cisco Systems, a former tech darling held up as a poster child for the tech-stock bubble, you'd be sitting on high-triple-digit gains -- way ahead of what you'd expect from non-equity investments.

I'm shocked, shocked to hear ...
Maybe that doesn't surprise you, but it sure surprised me. In fact, it's got me revisiting two long-held beliefs. The first visit resulted in an affirmation. The second was an epiphany. First, the affirmation.

At my age, I have to invest. For me, that means buying stocks, whether the market happens to look overvalued or cheap -- and not selling. That last part goes double whenever I manage to catch lightning in a bottle, like David did with AOL in 1994. And it does happen.

In fact, AOL wasn't the only home run in David's original Rule Breaker portfolio. He also picked Starbucks (NASDAQ:SBUX) and Amazon.com (NASDAQ:AMZN) in 1998 -- two other companies that revolutionized our lives. But take away that one 4,400% winner, and David looks human, right? More on that just ahead.

But first, the epiphany!
Slow and steady may not win the race. As you know, I typically side with David's stodgy brother Tom -- citing the money made on tried-and-true cash machines such as Johnson & Johnson (NYSE:JNJ) and data supporting Warren Buffett's steady-as-she-goes, win-by-rarely-losing value approach.

But I wonder: What if David's right to point out that on most nights, we only need a few big swings to win? Or, put another way: What if it's true that even if nine out of every 10 stocks we buy goes to absolute zero, we'll still break even if we find just one 10-bagger?

Well, it's a fact. Plus, what are the chances nine out of 10 of our companies will go belly-up? Not too good. And that's assuming we land a 10-bagger -- a rock-solid 1,000% gainer. Now, what if you smack a 4,400% home run? I'll let you run the numbers.

Because I have news for you ...
"The Tortoise and the Hare" isn't a true story. It's not even based on one. Take away AOL, Starbucks, and Amazon ... and David's pretty average. But that's crazy talk. You don't compare the batting average of a singles hitter with that of a slugger.

The fact is, David's kamikaze style works over the long run. And not just in the '90s. A few years back, David launched a new Rule Breakers newsletter to see if he could find this decade's great growth stories. How's he going to do it? He starts with a six-point checklist:

  1. Top dog and first-mover in an important, emerging industry?
  2. Sustainable advantage?
  3. Strong past price appreciation?
  4. Good management with smart backing?
  5. Strong consumer appeal?
  6. Has it been called overvalued by the media?

A stock with all six traits is a Rule Breaker in the making. Already, 10 of David and his team's picks have doubled, including three that have tripled -- putting his entire portfolio comfortably ahead of the broader market.

But David's never been about eking out a few points over the market. He's about hitting a handful of home runs and riding them into the sunset. Does that take guts? Sure, but I've seen him at work for a long time, and he's proven himself to me.
