Sound investing can make you very wealthy if you're not in too big a hurry

A pin lies in wait for every bubble. And when the two eventually meet, a new wave of investors learns some very old lessons: First, many in Wall Street (a community in which quality control is not prized) will sell investors anything they will buy. Second, speculation is most dangerous when it looks easiest.

I spend twelve hours a week - a little over 10% of my waking hours - playing the game. Now I am trying to figure out how to get by on less sleep in order to fit in a few more hands.

Traditional wisdom is long on tradition and short on wisdom.

Investors, of course, can, by their own behavior make stock ownership highly risky. And many do. Active trading, attempts to "time" market movements, inadequate diversification, the payment of high and unnecessary fees to managers and advisors, and the use of borrowed money can destroy the decent returns that a life-long owner of equities would otherwise enjoy. Indeed, borrowed money has no place in the investor's tool kit.
