What more would you like to learn?

I do not have any idea what I want to learn more and more because I just want to learn about useful thing. If I learned a lot of thing at once, it makes me confuse a lot. Such as windows, power point, and excel. These are enough for me. However, one thing what I want to learn that I strongly want it: which is HTML. I want to make more my web site. Moreover, I want to learn about how to protect from Virus, and also I want to learn more about mechanism of messenger.
