"Individual investors are constantly being exhorted to try beating Wall Street at its own game of trading like crazy to chase whatever is hot. But why should you bother trying to play a game that even most professional players can’t win?.
Instead, take a page from Mr. Spier’s book and play by your own rules. The faster Wall Street runs, the more you should slow down and step back from that madness. Buy and hold an index fund forever, or study a few stocks with all the peace of mind you can muster.
That way, you exploit the true advantages of individual investors that most professionals would kill to have: patience, independence and the ability to ignore the braying of the crowd."
