What you want to learn about computers?

First, I want to learn basic skills of computers such as MS Word or MS Excel because I'm sure that I'm a beginner, and they might help me do my job better in near future. Next, I want to learn E-mail. Now, I can send a e-mail by using my caller phone, but I'm not familiar with that of computer. I haven't felt its usefulness yet. In fact, however, it spreads to the public, so I want to learn how much useful it is. At last, I would like to deal with stocks to make some money. In public, some successful people with stock trading seem to be wonderful, but I know some lost their money by trading. However, it remains attractive to me because I can instantly make money by online trading, and it also thrills me. In the future, after I learn it very deeply, I will surely try it. By the way, I hate Takafumi Horie very much because I hate his belief, which means I can buy everything If I had much money.
