The Importance of Attitude in Investing

I think people are number one, people are usually very impatient. I think they get attracted by this daily liquidity of the stock market because you can buy and sell stocks, you know, 10 times a day if you want to at no cost now. And they become gamblers, not investors. So the key here is this. You want to have an attitude, this kind of attitude. If the stock market was closed for the next 10 years, would I still want to be making this decision? That's probably the most important kind of advice you can give in three minutes or less.
