The worst thing you can do is invest in companies you know nothing about. Unfortunately, buying stocks on ignorance is still a popular American pastime.

Everyone has the brain power to make money in stocks. Not everyone has the stomach.

It's human nature to keep doing something as long as it's pleasurable and you can succeed at it, which is why the world population continues to double every 40 years.

In the long run, it's not just how much money you make that will determine your future prosperity. It's how much of that money you put to work by saving it and investing it.

Twenty years in this business convinces me that any normal person using the customary three percent of the brain can pick stocks just as well, if not better, than the average Wall Street expert.

All the math you need in the stock market you get in the fourth grade.

It only takes a handful of big winners to make a lifetime of investing worthwhile.
