Many people invest in the stock market hoping to find the next Microsoft and Dell. However

, I know【21】personal experience how difficult this really is. For more than a year, I was【22】hundreds and sometimes thousands of dollars a day investing in the market. It seemed so easy. I dreamed of【23】my job at the end of the year, of buying a small apartment in Paris, of traveling around the world. But these dreams【24】to a sudden and dramatic end when a stock I【25】, Texas cellular phone wholesaler, fell by more than 75 percent【26】a one year period. On the【27】day, it plunged by more than $15 a share. There was a rumor the company was【28】sales figures. That was when I learned how quickly Wall Street【29】companies that misrepresent the【30】.

In a【31】, I sold all my stock in the company, paying【32】margin debt with cash advances from my【33】card. Because I owned so many shares, I【34】a small fortune, half of it from money I borrowed from the brokerage company. One month, I am a【35】, the next, a loser.

When all your stocks are doing【39】and you feel like a winner, you learn very little. It's when all your stocks are losing and everyone is questioning your stock-picking【40】that you find out if you have what it takes to invest in the market.
