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

Everyone has the brainpower to follow the stock market. If you made it through fifth-grade math, you can do it.

You get recessions, you have stock market declines. If you don't understand that's going to happen, then you're not ready, you won't do well in the markets.

Time is on your side when you own shares of superior companies.

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.

Imagine if you borrowed your parents' car without permission and ran it into a tree, how much better you'd feel if you were incorporated.

You should not buy a stock because it's cheap but because you know a lot about it.
