What I Want to Learn about Computers

I am interested in many fields of computers, especially program languages, Microsoft Excel, and computers' mechanism. First, I want to learn some program languages, like Java and C+ +, and I hope to make programs by using the languages. However, I think that it is very difficult to study the languages and use them well, so I will learn them very hard. Second, I would like to study Microsoft Excel. I am interested in mathematics and like it, so I want to calculate numerical formulas by using the software. I wish that I can utilize Microsoft Excel well and achieve my dream. Third, I want to know the mechanism of computers and how computers work. I have thought the mechanism for a long time, but I cannot understand it. In future, I hope that I comprehend the mechanism. Finally, I will study about computers hard, for satisfying my curiosity.
