Aspiration for Computer

I want to be a skillful user of computer in the classes and business in the future. As I mentioned, I can only use it to research and write for the assignments, but in the presence world, people must be able to use it for the business, such as management for the personal information, creating new ideas, designing, editing and so on..., which means if I can't use it as a business woman, I won't be able to get a job. I'm interested in the media, so if I get a job in the television company, I definitely need it for my job. Also, I'm really interested in the movie, such as how to edit the movie, how to create a commercial message, how to design the poster of the movie and how to create the computer graphics because it is the progress of the movies, and I really want to know about it to find out how the movie is made. Moreover, those effects are made by computers, and computers bring us new imagination of movies. Therefore, I'm really interested in supporting the creation of movie by computers. For now, I must practice how to use it for the class, and I want to master the basic usage of it. Furthermore, I want to learn it deeply for my professional skills for the future. Step by Step!!!
