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.

I think you have to learn that there's a company behind every stock, and that there's only one real reason why stocks go up. Companies go from doing poorly to doing well or small companies grow to large companies.

Visiting stores and testing products is one of the critical elements of the analyst's job.

The biggest winners are surprises to me, and takeovers are even more surprising. It takes years, not months, to produce big results.

Often, there is no correlation between the success of a company's operations and the success of its stock over a few months or even a few years. In the long term, there is a 100 percent correlation between the success of the company and the success of its stock. This disparity is the key to making money; it pays to be patient, and to own successful companies.
