You shouldn't just pick a stock - you should do your homework.

When you start to confuse Freddie Mac, Sallie Mae and Fannie Mae with members of your family, and you remember 2,000 stock symbols but forget the children's birthdays, there's a good chance you've become too wrapped up in your work.

I talk to hundreds of companies a year and spend hour after hour in heady pow-wows with CEOs, financial analysts and my colleagues in the mutual-fund business, but I stumble onto the big winners in extracurricular situations, the same way you do.

Your ultimate success or failure will depend on your ability to ignore the worries of the world long enough to allow your investments to succeed.

My method for picking stocks has never changed. When businesses go from crappy to semicrappy, there's money to be made.

A stock market decline is as routine as a January blizzard in Colorado. If you're prepared, it can't hurt you. A decline is a great opportunity to pick up the bargains left behind by investors who are fleeing the storm in panic.

If you can follow only one bit of data, follow the earnings - assuming the company in question has earnings. I subscribe to the crusty notion that sooner or later earnings make or break an investment in equities. What the stock price does today, tomorrow, or next week is only a distraction.
