Have the courage of your own convictions and don't be swayed by friends who boast about their financial home runs. Last year's winners are often this year's losers.

Never call your broker on Monday. Out of courtesy and common sense, wait until Tuesday. A good broker is focused on the opening of the market - at home and around the world - and on getting back into a business frame of mind after the weekend.

Bulls make money and bears make money, but pigs seldom do. When a stock or mutual fund is up 30%, sell one-quarter of your position.

Invest less at the end of the month. Brokers tend to push stocks at the end of the month in an effort to match or surpass their previous month's sales.

Invest in vanity. Buy stocks in high-profile companies whose products are designed to make you feel good and look good.

Avoid greed and fear. These are the investor's Achilles heels. Keeping all your money in the bank earning 3% interest is just as foolish as dumping your entire savings into the market thinking you'll make a quick buck.
