The article "My Dividends Are Bigger Than Yours" always makes me smile. Many of my pieces review the boneheaded blunders I've made in my investing life. But that one covers something I did right: Buying a healthy, growing, dividend-paying company -- and hanging on tight.

The stock in question is Johnson & Johnson, which I bought for about $43 in 2002. The stock has since climbed to around $67 per share, offering today's investors a respectable dividend yield of around 2.7%. As I explained, though, my dividend yield for Johnson & Johnson is approximately 4.3%. Better yet, I suspect it might be 13% or more in just 10 years.

Since I paid $43 per share, and I now receive $1.84 per share in annual dividends, I figure my yield is now 4.28% ($1.84 divided by $43). Better still, as the dividend grows over time, my effective yield will also grow. (It was 3.9% just a little while ago.)

The power of time
I'm not the only investing genius around, though. Plenty of investors -- like Bob W., who emailed me after reading my article -- figured out the power of dividends long before my own light bulb went on.

Remember how I got my shares of J&J back in 2002? Well, Bob bought shares of General Electric in 1987, a full 15 years earlier. What's his effective yield today? Roughly 30%! (I bought General Electric, too -- in 2006. My otherwise respectable 3.3% effective yield pales in comparison.)

Furthermore, Bob's Wells Fargo shares, bought in 1986, now bring in an effective yield of 61% relative to his original purchase price. Around the same time, he bought into a major bank, today reaping an effective yield of 45%. He also snares a 79% yield on a telecommunications company.

What's his secret? Well, like I did with Johnson & Johnson, he bought into healthy, growing, dividend-paying companies, and hung on. Note that most of the purchases he mentioned to me were from 1986 and 1987. He didn't specify exact dates, but I wouldn't be too surprised if he managed to snag shares of great companies soon after the "Black Monday" crash of October 1987.

Start yesterday, start today, start now
If you're feeling any pangs of jealousy right now, go research companies that interest you -- some may end up being stocks for the rest of your life. The first months of 2008 haven't been too kind, and many great companies have seen prices plummet.

When prices fall, yields rise, making this a particularly attractive time to find some great dividend payers. (Look also for companies that have been hiking their dividends regularly and significantly.)

Here are a few companies from a screen I ran for firms with yields greater than 2%, P/E ratios of 20 or less, net profit margins greater than 10%, and estimated earnings growth rates for the next five years of more than 10%:
