First notebook entry: Introducing myself

Outside of what Sissy edited, these are my edits:

I am come from China (The phrase "I come from China" makes sense, but "I am from China" sounds more natural.)

I am outgoing, humorous, hardworking rigorous. (We don't use "rigorous" to describe  one's personality. Usually it describes something that is difficult to do, for example a rigorous math course, rigorous exercise, etc...)

First notebook entry: Introducing myself

I come from China. I graduated from university in Shanghai, where I majored in computer technology and science. I like making friends with different people; I like reading, travelling, and doing sports. I am outgoing, humorous, and rigorous.
