We've asked each of our bloggers to introduce themselves and talk a little about why they love the market and what positions they call their own. We encourage our bloggers to own common stock and abide by a common code of conduct.

Who are you, and why are you passionate about stocks?
My name is David Kretzmann and I live in Nevada City, CA.

I enjoy investing in stocks because I feel they are the best choice for long-term investors. For each stock in which I invest, I have a minimum of a seven-year time frame placed with that stock, because I believe that is the time you should let a stock "run." I have always liked the idea that you can actually invest in your favorite companies, whether it be Starbucks, Whole Foods, or Palm. It is a fun way to see your money grow.

What was the first stock you owned?
I first starting investing in stocks last July when I was 12 years old, starting by investing in a total of nine different companies (which was a mistake, because I didn't do nearly as much research as I should have). Some of those companies included Palm, 7-Eleven, Netflix, and Electronic Arts. All of the stocks I invested in were recommended by either David or Tom Gardner of The Motley Fool from their various newsletters.

What was your worst investment ever?
I haven't had that terrible of an investment yet, because I've only sold a stock twice (AT&T and Cutter & Buck), and you don't lose any money on an investment until you've sold. So, I haven't had any disappointing investments yet. Only if in seven years I see one of my investments is down, will I consider it not-so-good investment.
