All you need for a lifetime of successful investing is a few big winners, and the pluses from those will overwhelm the minuses from the stocks that don't work out.

The stock market really isn't a gamble, as long as you pick good companies that you think will do well, and not just because of the stock price.

There are substantial rewards for adopting a regular routine of investing and following it no matter what, and additional rewards for buying more shares when most investors are scared into selling.

You have to keep your priorities straight if you plan to do well in stocks.

If a picture is worth a thousand words, in business, so is a number.

A price drop in a good stock is only a tragedy if you sell at that price and never buy more. To me, a price drop is an opportunity to load up on bargains from among your worst performers and your laggards that show promise. If you can't convince yourself "When I'm down 25 percent, I'm a buyer" and banish forever the fatal thought "When I'm down 25 percent, I'm a seller," then you'll never make a decent profit in stocks.

That's not to say there's no such thing as an overvalued market, but there's no point worrying about it.
