Everyone has his own plans and ambi

Everyone has his own plans and ambitions. People want to be a doctor, other want to be a teacher. I’m 20 years old now and I think I’m old enough to have the plans in the future.

I’m in my second year and study at IT. Of course, in the future, I want to be a good computer engineer. First, I’m going to study many programs of computer. Beside, I will learn another languages, especially English, because it’s useful with my jobs.

After graduating from University, I want to work for a large company such as FPT. I’ll create the most famous viruses.And I hope , it'll kill all other viruses. Then, I want to have my own computer shop. In my computer shop, there are every kind of computer's spare-parts such as: Ram, USB, printing machine , loudspeaker , mouse , keyboard, disk, electronic chips of computer ... Finally , I want everybody in the world to know me.

I have slightly tweaked an already well-edited job by you:

Everyone has his own plans and ambitions. Some people want to be a doctor while others want to be a teacher. As for me, I’m 20 years of age and old enough to have made a plan for my future.

Currently, I am a second year student majoring in IT. I certainly wish to become a good computer engineer in the future. Toward that goal, I am going to study hard and master as many computer programs as possible. Moreover, I will learn a foreign language, especially English, because it will be quite useful in my job.

After my university graduation, I want to work for a large company such as FPT. I will create the most famous anti-virus program, one that can exterminate all other viruses. Then, I will have my own company that carries all kinds of computer spare parts and accessories such as DRAM’s, USBs, printers, mouse, keyboards, loudspeakers, ROM and RAM disks, chips, motherboards etc. Eventually, I want everybody in the world to recognize my name.
